The components at 5:03 are an "inlet capillary", "tube lens" and "skimmer". The inlet pulls ions into the vacuum chamber from the Electrospray ion source. As ions exit the back of the inlet, they enter the first vacuum chamber at ~1 Torr. Here the "tube lens" creates an electric field that focuses the ion beam through a small hole in the "skimmer". As ions leave the back of the skimmer, they're in the second vacuum chamber, probably at low mTorr pressures. Here they enter the "octopole ion guide", which you referred to as "where the magic happens". This ion guide focuses the ion beam through a small hole at the back of the second vacuum chamber, so that ions efficiently get to the third vacuum chamber, where the "quadrupole ion trap" performs the actual mass analysis.
It's just like Christmas when Mike uploads a vid! Will settle down with a nice meal and chill out to some secret life of tech. Cheers Mike (ya legend!)
Ok, that is 2 or 3 times the complexity I had originally anticipated for a mass spec. This has now motivated me to understand the operation in greater depth.
Regarding the DIN plug and DC power jack, it might be an interesting video going over different connector types for different purposes, discussing reliability, price etc about them. This because you have quite a lot more experience than the average viewer in robust industrial equipment, and info about that is rare and mostly gotten through experience.
I would rather want standard connectors rather than "expensive because we say so" bullshit. Sure there's no point in aggressive cost optimization for small series production, but that board with a 9V rechargeable battery was ridiculous. There _got_ to be more of bullshit like this in that device.
i would say that the dc jack was suprising though, afaik its just like with phono jacks where basicly the positive can(does) connect first rather than ground so puts both sides at risk from each other in all sorts of ways
Those little blocks of green indicator LEDs on the huge board are nice. I can find rectangular LED bargraphs in DIP but nothing like those little round ones.
I can't wait for Part 2 because I worked on the design of a similar single quad about 7 seven years ago. There is some stuff, like that tesla coil that I just can't wrap my head around. There's also a lot more RF than we used in a similar vintage mass specs. I like seeing other peoples solutions to the same problems. Of course things have moved a long way forward since this instrument.
Regarding the pump being built into the unit: since this is a mass spectrometer, they have to use a special vacuum pump which does not have oil in any of the active components, otherwise there would be way too much organic trash in the mass spectrum (all the cracked derivatives of mineral or silicon oil) which would totally falsify the results. Btw, you got your moneys worth even in Aluminum, not even talking about all that electronics.
I used to work with the low end single quad mass spec the aqa model, which was about £40K back in the day. So this one when new was about £60-80K with the HPLC System costing another £20K. I think this one is an early ion trap model, so it can do ms to the n which means it can break apart the charged molecule into chunks and break those chunks up. That helps chemists work out the chemical structure. I never got the work with cool equipment like this. When it was new it was probably running 24 hrs a day doing analysis for pharmaceutical companies clinical trials ect. I should pony up some cash for Mike's patreon.
That tesla coil, the ceramic plate looks like a 'topload' but with the 'ground plate' which they take the sample voltage from. I would bet you could run that as a standard tesla coil if you located the electronic driver circuit. The bottom coil is probably the primary, the next small coil is probably the feedback, the primary is probably tuned by that plate.
I wonder, when planning a product like this, do they know all of the components they may need, or do they add stuff on as they go along to make the whole thing work? Seems like a ton of steps just to do some spectrometry. Also, are there any potential cost savings if you do a single massive PCB instead of a few smaller ones?
21:53 one can see that they have left Capton tape on PCB below the IC, so either they repaired something, or the PCB is hand made. One would naively think that for such a high end equipment they would pay more attention, but actually these devices are built in such low quantities, that almost all of them are kind-of a prototype.
Not sure if I can find the control software for this old mass spectrometer, but I am sure that Xcalibur 2.2 is available for download, which contains the thermo acquisition services, qual browser for data preview/analysis, etc. If you are interested in powering it up and collect some mass spectra, I can dig around for the software.
"The PA85 is constructed from MOSFET transistors. ESD handling procedures must be observed. The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes."
I for one though you were going to get it up and running and actually using it, but looking at the internals is always fun. Sadly there's nothing like this available where I live and shipping from where you can get one would cost way too much...
Hello Sir, Great videos. (Question about the M3863A FR2), Could someone just replace the basic Panasonic CR123A camera batteries with new ones rather than spend $260 on a new battery?
i recognized that sbc from the first little view of it those things are tanks and in tons of lab gear lots of options for user code on eproms and other storage methods
I am not sure the software for this thing is on that EEPROM. Maybe the strata flash chip. But I would not be surprised if this thing does netboot. Around the time this thing was made I designed some embedded devices that were PC based and managed to get Ethernboot in a small ROM along with a very primitive BIOS I wrote. Enough to boot VxWorks via TFTP. In that era this approach made sense.
that LC pump is probably for a liquid chromatography pump for LCMS (liquid chromatography-mass spectrometry) which is a common technique used in chemistry
Pretty nice find! I'm always amazed at how well the wiring is laid out in those things... BTW, if you're not doing anything with that 486DX CPU card... ;)
Hey Mike, very cool. Unlike the Roche kit there's actually quite a bit of electronics in this unit. Would be interesting to see if you can get the turbo vacuum pump running and maybe create a few sparks from the mini Tesla coil. Totally know what you mean by ending up with a huge load of parts after a teardown!
I *thoroughly* enjoyed this! I virtually NEVER subscribe to a channel based solely on one video (especially on a video that's a few years old), but I *loved* this, and I will be looking out for your videos from now on! 😄 As a researcher (neurobiologist specializing in psychopharmacology), I have purchased similar old lab equipment from eBay for my home lab, and have also done my fair share of tinkering, but probably not to the degree that you have (based solely on your level of experience given your commentary)! Forgive me if I missed this in the intro, but, did the seller have any idea what was wrong with it? Were you able to determine why the machine was scrapped, or what might have been needed to repair it? Do you have any rough guess of what it might cost to get it running again? I have been looking at a few scrapped mass specs, myself, but I'm not sure what I would be getting myself into, as my comfort zone is in optical spectrometry/spectroscopy... Any information would be greatly appreciated!
Cody'sLab could purchase something like this and have quite cheaply some high quality vacuum devices if in working order like pump, measuring gauge, valves, electrical feedthrough connections.
When looking at boards, *PLEASE* try to hold them still (or better yet, put them down). When you're hand-holding them, the small movements mean the fine details and part numbers become unreadable because of video compression artifacts.
agreed, Mike has always been like this, it's frustrating but I reckon that's how his brain works :-) as for you Connor, where the frig are your videos ? I love your stuff but it's even rarer that Mikes ... prod prod :-) :-)
Not only do I remember 10-base-2 ethernet, but about 2 years ago, I threw out a whole box full of those exact same SMC ISA network cards! I think I kept a couple for nostalgic reasons!
gorak9000 I remember back in high school us ultra nerds helped out setting up some LAN nodes via AUI because we had a whole bunch of that rather than cheaper 10-2 or Cat 3 cable for some strange reason. XD
I don't think I've ever seen the big cable with the clamp on taps on it. I think there might have been one clamp on tap on the "history museum" shelf in my lab in grad school, but I never had a good look at it. I heard it was quite the thing! When I was in high school, it was all 10-2, and right at the very end, they were switching it out for cat5. A bunch of those rg-58 cables ended up in my collection, and now serve some light duties for test bench use, or HD-SDI or ASI (yup, that's right, 50 ohm coax for 75 ohm signals, tisk tisk!!), or other interesting things! Kind of a shame most of the bnc connectors were so poorly crimped... when I run out of cables with 2 ends, I'll think about buying some ends and re-crimping some of them :)
44:36 minutes in only -- That "Tesla" coil has to be the ion accelerator? Can you find the deflector magnets and detector screen? it would be nice, for part 2, if you identified the sample inlet, heater, electron source (ionizer), accelerator, deflector magnets/electromagnets and detector. Fantastic to see how these things look like inside, when all the knowledge you have are the theory of operation basically.
TheAmmoniacal that's a transformer for creating high amplitude rf (hundreds to thousands off Vpp) to drive the "ring electrode" of a quadruple ion trap, which if what the LCQ uses for mass analysis.
TheAmmoniacal on the LCQ, ions are generated outside of the vacuum chamber, usually via electrospray ionization, and are then pulled through a differential pumping system until the arrive at the ion trap.
I always wondered if the engineers who once worked on all of these projects, watch Mikes videos, knowing the pain and challenges behind each design decision. I imagine each little remark and comment Mike makes took hours and days of designing, meetings and conflicting opinions until it makes it to the product.
I found an octapole out of a Finnigan LTQ FT Mass Spectrometer on ebay (by randomly searching for "octapole" on Google images). That guy wants 150$ for it without any guarantees. So considering you got the whole machine for twice, maybe three times that, you got a bargain ;) .
It's not really a tesla coil, that's a resonant design, in this the RF coil is fed with an RF signal and there's a tunable ballast inside that peaks the output, which is then fed to the octo-rods (I think) I used to test, calibrate and repair the Micromass version of this a long time ago (a much nicer design)
I don't understand why you can't bench test that HV op amp? Such a waste to tear it apart. btw what's your eBay name, presumably you offload some of these bits eventually.
do any of these companies ever reach out to you to tell you how correct/incorrect you are? they must find it somewhat cool that someone and their audience is that interested in their project
Eric Gibson it's a mass spectrometer. The clue is in the name. It basically ionizes a samples of stuff and then through mass to charge ratio is then able to determine what elements a sample is made of. Simply it ionizes stuff and is able tell what something is made of by spectra of the isotopic signature of the sample of stuff you put into it.
Sionyn Jones it sounds like it makes material into a light and if its red it's iron and if it's blue it's water? Or is mass weight and it says it's red if its heavy and blue if it's light?
Eric, what you are thinking about is spectro*photo*meter. In MS you are separating ions by mass to charge ratio (m/z) and then they hit the detector you get the intensity (ion count) at given m/z. You can then figure out mass by analysing the spectrum (deconvolution) and - hopefuly - determine the identity of analyte. Only place when light has something to do with MS is if you have a scintillator and light amplifier as your detector.
Cost doesn’t matter, but jeez you’d think shaving a few thousand of the build would make someone happy, especially when it wouldn’t be that difficult... this is why we pay $1500 a month for decent medical insurance in the states... they just pass all the waste down to the consumer.
8:35 All that heavy super-precision awesomely-complicated insanely-expensive-in-it's-day machinery, and that tiny little curl of very thin tubing is the main link in the whole friggin' system?, ...and the mega-geniuses that designed that heavy super-precision awesomely-complicated insanely-expensive-in-it's-day machinery could not even design-in a guard shield around that tiny little curl of very thin tubing? ;-)
....i just sat through an hour of a teardown.... i dont even own a mass spectrometer! this is of no use to me! btw, you should make a "little" tesla coil out of the coil from it, preferably with audio driven output
can you change lens or zoom out when not necessary. It's very hard to watch your interesting videos. Also when talking about a circuit board such as the led board, could you please keep stuff stationary and in picture so that what you talk about can be viewed. Please less motion, no unnecessary zoomed in stuff, change to wider lens, I'm certain im not alone getting motion sickness.
Can't be bothered with ebay - if you're in the UK you can have them for the cost of postage - email me. Ones from this are 24V but I probably have others
Could you please stop videoing freehand, you've got a wobbly camera position and on top of that you always wobble the board around as you speak. Just put it on the table and use an overhead camera. And please stop scanning across a PCB in super-fuzzy-o-vision, it's hard to follow.
The constant meaningless cut edits between sentences make this video impossible to watch. I would rather have a child continuously hit my head with a stick. NEVER cut edit from one scene to the exact same scene if you have any self respect. Are you trying to be PewDiePie?
First Last try looking at any professional production. Any one. Are you that much of a dolt? My shows were all on cable TV, before internet video existed. All the shows I've directed (well over 100) have been three camera shoots done in studio with a full studio crew. When you do it right to begin with you don't need editing. You can take your head out of your ass now.
The components at 5:03 are an "inlet capillary", "tube lens" and "skimmer". The inlet pulls ions into the vacuum chamber from the Electrospray ion source. As ions exit the back of the inlet, they enter the first vacuum chamber at ~1 Torr. Here the "tube lens" creates an electric field that focuses the ion beam through a small hole in the "skimmer".

that's great information. thank you.
It's just like Christmas when Mike uploads a vid!
Will settle down with a nice meal and chill out to some secret life of tech.
Cheers Mike (ya legend!)
yep!
The vent delay at 29:37 may also be to allow the turbo pump to spin down a bit before it gets full atmospheric pressure.
Ok, that is 2 or 3 times the complexity I had originally anticipated for a mass spec. This has now motivated me to understand the operation in greater depth.
Regarding the DIN plug and DC power jack, it might be an interesting video going over different connector types for different purposes, discussing reliability, price etc about them.

Lab equipment devices are sometimes made full of BS just to look more kool to milk some more money out of the customer, I guess.
i would say that the dc jack was suprising though, afaik its just like with phono jacks where basicly the positive can(does) connect first rather than ground so puts both sides at risk from each other in all sorts of ways
Yes ! It's instrumentation time again.
When you work in a lab, you get play with so much awesome equipment but they never let you dig deep in them.
They're waiting for you Mike.... In the test chamber.
Mike doesn't need to hear all this. He's a highly trained professional. :)
I can't think of a better way to spend a lazy Sunday afternoon! Ta very much!
Another great teardown, looking forward to part 2!
great to see you back again mike
I've been wanting to see this! You get the best stuff Mike
Those little blocks of green indicator LEDs on the huge board are nice.
I can find rectangular LED bargraphs in DIP but nothing like those little round ones.
www.goldmine-elec-products.com/prodinfo.asp?number=GP36
Wow, that's a lot of black magic happening inside that box - I can't wait for part two!
I can't wait for Part 2 because I worked on the design of a similar single quad about 7 seven years ago. There is some stuff, like that tesla coil that I just can't wrap my head around. There's also a lot more RF than we used in a similar vintage mass specs. I like seeing other peoples solutions to the same problems.

Mike: Tearing down and explaining things i didnt even know existed...
Regarding the pump being built into the unit: since this is a mass spectrometer, they have to use a special vacuum pump which does not have oil in any of the active components, otherwise there would be way too much organic trash in the mass spectrum (all the cracked derivatives of mineral or silicon oil) which would totally falsify the results.
Btw, you got your moneys worth even in Aluminum, not even talking about all that electronics.
40:50 possibly a variable cap to change capacitance or reactance?
I used to work with the low end single quad mass spec the aqa model, which was about £40K back in the day. So this one when new was about £60-80K with the HPLC System costing another £20K.

When it was new it was probably running 24 hrs a day doing analysis for pharmaceutical companies clinical trials ect. I should pony up some cash for Mike's patreon.
The sound Mike made at 31:12 was too funny, you can tell that got him a little excited.
Another laugh at 47:50, "high end lab equipment" "DC power jack" "DIN plugs", " Seriously!"
That was just too funny, at least to me.
I saw this exact machine on ebay last week and thought of you, and then hey what do you know it show up! excellent!
Looking at those precision machined parts.... just awesome. Real science and engineering there, worth every $$$$$$$$$$
Really nice kind of equipment you got there
WOW the coolest teardown ever :-)
Wow, you sure do find nice stuff!
That tesla coil, the ceramic plate looks like a 'topload' but with the 'ground plate' which they take the sample voltage from.
I would bet you could run that as a standard tesla coil if you located the electronic driver circuit.
The bottom coil is probably the primary, the next small coil is probably the feedback, the primary is probably tuned by that plate.
This one has by far the highest 'oooh' factor yet! :D
I wonder, when planning a product like this, do they know all of the components they may need, or do they add stuff on as they go along to make the whole thing work? Seems like a ton of steps just to do some spectrometry.
Also, are there any potential cost savings if you do a single massive PCB instead of a few smaller ones?
Mike did you have anything to do with the light display at the new Southampton mall? It was made by Cinimod Studios
Much smaller than the one in Half-Life.
Always love to see the guts of scientific equipment. The industrial PC was rather interesting.
Ever since I heard of them, I've always wanted a Mass Spectrometer.
Nick Drudge The university I work at has two for sale on their surplus site :)
just subscribed to your channel I have worked in mass spec for years so very interested in this
21:53 one can see that they have left Capton tape on PCB below the IC, so either they repaired something, or the PCB is hand made.

Definitely didn't expect to find a Tesla coil in there. Neat!

Was there a primary coil for the tesla coil? Seems like there was only the big secondary coil.
That machine's innards are a total nightmare. The B.O.M. must have been enormous.
i recognized that sbc from the first little view of it
those things are tanks and in tons of lab gear lots of options for user code on eproms and other storage methods
I am not sure the software for this thing is on that EEPROM. Maybe the strata flash chip. But I would not be surprised if this thing does netboot.

I read the EPROM and it looks like just BIOS. The manual mentions downloading software from host PC so probably right about net booting.
What happened to part 2 ?
that LC pump is probably for a liquid chromatography pump for LCMS (liquid chromatography-mass spectrometry) which is a common technique used in chemistry
Pretty nice find! I'm always amazed at how well the wiring is laid out in those things...
BTW, if you're not doing anything with that 486DX CPU card... ;)

Wow ISA and BNC networking. That takes me back.
"You youngsters might not remember this" ... unfortunately I can, just about :(
*shakes cane* In my day we had to terminate our networks.
VICI still uses the barrel and DIN connectors 20 years later on micro-pumps and such, probably just to keep backwards compatibility at this point.
55:45 I have to replace this supply in our spectrometer lmao
GUESS WHO'S BACK
BACK AGAIN
Mike?
Mike is back, tell a friend.
Mikes disassembled a monster, 'cause nobody wants to see assembled products no more
DIN Plugs?
It's always such a pleasure...
I *thoroughly* enjoyed this!

The coaxial D plug is used on Sun Systems as a monitor connection.
Ah the good old day's when monitors weighs over 35kg. ;)
part 2 ?
Mike,what do you keep from teardowns?i think you have a metric fuckton of stepper motors
Yep - have a big pile of stuff to go on ebay when I can be bothered
i would love to see you build a 3d printer.but do it mikeselectricstuff style.no commercial crap.
With the stuff he's collected, he can build a 3d printer to print atoms :-)
I wonder if that coil could be repurposed as tesla coil?
Cody'sLab could purchase something like this and have quite cheaply some high quality vacuum devices if in working order like pump, measuring gauge, valves, electrical feedthrough connections.

Are you using a new camera?
I dont get as seasick as i use to get watching your teardown videos.
Yahoo !! Thanks for the new video ! Compliments Mike! (p.s. i hope you received the flir)
How big is you house mike with all that stuff :)
i have a similar fan collection, i am going to make a computer case out of them
I always wondered if the engineers who once worked on all of these projects, watch Mikes videos, knowing the pain and challenges behind each design decision. I imagine each little remark and comment Mike makes took hours and days of designing, meetings and conflicting opinions until it makes it to the product.
Hey Mike, as much as i like your Videos and extraordinary hardware, can you pleasy buy a 1080p camera and try to use less shaky videos? plleeeease :)
actually used this unit in my day the cost back in the 1990's was about $500,000 US
16:00 It will give a nice dispenser for flux or something like this.
Sometimes you discover a CZcams channel, and just say to yourself "this is the real deal". : )
Even brand new modern mass specs, are practically identical to this model, and most use designs that are decades old
Sweet db5w5 never knew they came with no standard pins.
Oddly enough I finished work with an LC based company last week, and starting with a mass spec company tomorrow... coincidence?!
I found an octapole out of a Finnigan LTQ FT Mass Spectrometer on ebay (by randomly searching for "octapole" on Google images). That guy wants 150$ for it without any guarantees. So considering you got the whole machine for twice, maybe three times that, you got a bargain ;) .
The Tesla coil would be used to ionise the gases inside the chamber.
douro20 no it's to generate rf waveforms for the quadrupole ion trap that performs mass analysis.
*grin* The 'Ooooh' realy does it for me this time :-D
It's not really a tesla coil, that's a resonant design, in this the RF coil is fed with an RF signal and there's a tunable ballast inside that peaks the output, which is then fed to the octo-rods (I think)
I used to test, calibrate and repair the Micromass version of this a long time ago (a much nicer design)
11:11 cheapernet, thin ethernet.
Interestingly enough I'm still selling this cable in reels of 50m and 100m for military purposes.
I'd be a little wary about touching the inside of the sample injector assembly without gloves.....
Apex loves to use deadly beryllium oxide in their amplifiers
what is used for? Just analysing materials?
Damn.. these machines are state of art...
This thing looks pretty big, but from the diagrams shown in chemistry in school, I was expecting something even bigger.
Good ol fashioned rant at 47:50
Given how impressive that machine is I would have forgiven them for the odd DIN connector on a stepper motor.
Considering the user doesn't even interact with the connector, I have zero complaints.
I've never seen a board that huge!...Kept thinking how funny it would be to drop that on a work bench for an apprentice -CLUNK!....fix it.
Spending a tiny bit of the money on a tripod would make the jumpcuts a little less obvious ;)
I don't understand why you can't bench test that HV op amp? Such a waste to tear it apart.
btw what's your eBay name, presumably you offload some of these bits eventually.
do any of these companies ever reach out to you to tell you how correct/incorrect you are? they must find it somewhat cool that someone and their audience is that interested in their project
we need to get you an electric screw driver
Lets look inside here: Wuuuooh
be careful with the APEX hybrid modules. The ceramic in them is probably beryllium oxide which dust is highly toxic.
welp, this is loads more complicated than an old CRT TV...
What does this machine do?
Eric Gibson it's a mass spectrometer. The clue is in the name. It basically ionizes a samples of stuff and then through mass to charge ratio is then able to determine what elements a sample is made of.

Only place when light has something to do with MS is if you have a scintillator and light amplifier as your detector.
Put that pex thru the x ray machine :) nvm, you cracked it open
Damicske I died a little when cut the hv opamps open. 😨
Cost doesn’t matter, but jeez you’d think shaving a few thousand of the build would make someone happy, especially when it wouldn’t be that difficult... this is why we pay $1500 a month for decent medical insurance in the states... they just pass all the waste down to the consumer.
8:35 All that heavy super-precision awesomely-complicated insanely-expensive-in-it's-day machinery, and that tiny little curl of very thin tubing is the main link in the whole friggin' system?, ...and the mega-geniuses that designed that heavy super-precision awesomely-complicated insanely-expensive-in-it's-day machinery could not even design-in a guard shield around that tiny little curl of very thin tubing? ;-)
....i just sat through an hour of a teardown....
i dont even own a mass spectrometer! this is of no use to me!
btw, you should make a "little" tesla coil out of the coil from it, preferably with audio driven output
can you change lens or zoom out when not necessary. It's very hard to watch your interesting videos. Also when talking about a circuit board such as the led board, could you please keep stuff stationary and in picture so that what you talk about can be viewed. Please less motion, no unnecessary zoomed in stuff, change to wider lens, I'm certain im not alone getting motion sickness.
I can take some fans off your hands! Any 120mm ones, put them up on Ebay
Can't be bothered with ebay - if you're in the UK you can have them for the cost of postage - email me. Ones from this are 24V but I probably have others
FIrst?Best sunday ever
Hahaha... Thumbs up!
ill come back when you stop breathing in you mic.
Could you please stop videoing freehand, you've got a wobbly camera position and on top of that you always wobble the board around as you speak. Just put it on the table and use an overhead camera. And please stop scanning across a PCB in super-fuzzy-o-vision, it's hard to follow.
The constant meaningless cut edits between sentences make this video impossible to watch. I would rather have a child continuously hit my head with a stick.
NEVER cut edit from one scene to the exact same scene if you have any self respect. Are you trying to be PewDiePie?
Peter S I just went to watch videos on your channel to see this perfect editing in action, but unfortunately you don't have any videos.
First Last try looking at any professional production. Any one. Are you that much of a dolt? My shows were all on cable TV, before internet video existed. All the shows I've directed (well over 100) have been three camera shoots done in studio with a full studio crew. When you do it right to begin with you don't need editing. You can take your head out of your ass now.
When I directed Lord of The Rings I did it all in one take too so it didn't need any editing. I used 4 cameras though.
Another brilliant and informative teardown of niche equipment. shame I could not stop giggling at the connectors labeled "ANAL "
John Hamblett that just means you're human. . . or kinky. :p
