I do my work with formaldehyde 37%, I need to measure concentration by using Gas chromotography, how I choose proper solvent in this work. Can explain me sir
Thank you for your answer. I mean that my sample I will collecting is gas after that this gas sample I will inject to GC-FID. But mostly I saw on video people post is the use of a solvent, not a gas ??? So anyone here can help me. Thank you
Goodness gracious! The information is amazing but this is the most horrible, annoying and loud music I've ever heard in CZcams videos. Pleeeease no music. Thanks God and technology for close caption
bruh the music! once that beat dropped I got up off my chair and started vibin'
this music is great for vibin' in the chem lab
This is a well done video. I enjoyed it. Thanks!!
best train of GC . Thanks
Why ethyl benzene is used?
Super
Do we have to use new microsyringe when changing samples ?
i would think so, as to not contaminate samples.

Music is too irritating
how to inject if your sample is on gas not liquid?Thank you
Carlagoncalves Carlagoncalves if sample is a gas one way is to condense it. Another way is to use an absorbent material to absorb gas.

@@carlag07 fill a baloon and connect it to the special inlet
@@carlag07 use sampler for gas or condom for balloon.
@@mohsenziarati3046 Thank you for your information 👍🏿 I have completed the project 2 years ago. I Really appreaciate it👍🏿
My dream is to get in NUS.Can u tell how should i get in ? Currently,i am doing chemical engineering from IIT Kanpur in India.
Can we detect the oil samples?
The boiling point of the compounds for GC should be less than 300 deg C. Quite volatile.
thanks but too much background music!!
