Rapid Detection of Microplastics (MPs) in Water Samples
In this video, we demonstrate a rapid and precise detection of microplastics in water samples using the Agilent 8700 LDIR chemical imaging system. This emerging technique greatly minimizes human error, reducing the chances of misinterpreting microplastics in water samples and enhancing confidence in the accuracy of the results. #microplastics #LDIR #Agilent #waterquality #watersafety

Thank you for the nice video. I had a few question 1) thickness of the sheet how to increased is it directly depended on time 2) Can we use MPD or OPD to get more efficiency in RO 3) can we use COF or MOF in this mixture to increase more efficiency for this sheet.
hello sir/maam, may I ask? I'm currently casting a membrane from cellulose acetate and NMP solvent, but I'm having a problem. After I cast it and then put it in a coagulation bath, my membrane sticks to the glass plate. Is there a solution that I can do to prevent the membrane from sticking to the glass plate?
You can consider using a larger coagulation bath. This might be helpful to solve your problem.
@@morethanpurity1770 i used a bigger coagulation bath, i even put a lot of distilled water in the coagulation bath and it still didn't work. is there another solution i can try to prevent the membrane from sticking to the glass plate?

Hi, very usefull! One question: for TFC membranes, from which direction do you cut through the sample? First through the selective layer?
@scoutcaspers4859 It does not really matter which direction you start as the membrane is already embedded within the resin.
Good job👌👌
Fantastic!!

Can you please tell me from where we can buy this type of stainless module for hollow fiber potting?
Hello, very interesting video. I am just wondering that the feed solution looks more conductive than the draw solution, so how the water is drawing from feed to draw.
@shubhamketansharma2314 .Thank you for your interest. Actually, the feed solution is significantly less conductive than the draw solution. The highly saline draw solution creates the osmotic pressure difference which induces water to flow from the feed solution through the membrane. If the osmotic pressure of feed is higher than the draw solution, feed is not able to be drawn to draw side.
Can you please tell me how you calculate the reverse solute flux with its initial and final concentration values

The non-woven is made of polyester. We did not produce non-woven. We bought it from market.
Good video! May I know what the water is? How long you soak the membrane into the water? And what temperature did you use in the oven?
The fabrication conditions vary depending on the researchers' approach, but in our case, the conditions are as reported in this paper - www.sciencedirect.com/science/article/pii/S0011916421005737?via%3Dihub.

Dear sir , Thanks for the video . very great . one question . Can i reuse this two solutions once again for membrane preparation . if, How much time , i can reuse this . Give advise please .
Yes, you can. But we advise you to prepare a fresh one after 1-2 hours you use the solution.
Can the TFC stick to porous acrylic surfaces?
Hi @Loyd, it would not stick to acrylic surface. This is because the bottom (adhering to acrylic plate) of TFC membrane is made of non-woven fabric and this material will not have reaction with acrylic.
It would be better to consider a protective layer on the surface of the glue (at the end of the fibers) to ensure that the surface of the fibers does not react with the glue, and it can also prevent the end port of fibers get damaged when it vibrates during operation.
Thanks for your comment. Can you suggest the material that can be used as "protective layer"?

Good Job again...simple yet infomati ve. keep up the good work. Hope this will be benefit others.
This is a great video! Thanks for the upload. I am new to the field of membrane production and have some questions, and it would be nice to hear your comment on them: 1) How do you control the thickness of the different layers since you pour the monomers in excess on the surface. Is the thickness just correlated to the reaction time? 2) Do you use these TFC membranes for (RO) water filtration applications? Thank you again for sharing your knowledge, highly appreciated!
Hi Florian. Thank you for your message. Can you please contact me via email (lwoeijye@utm.my)?
The IP technique is used to create the polyamide layer only. Other layers such as the susbtrate layer uses other fabrication methods such as casting. In IP, various factors (such as reaction time, concentration of monomer solution used, post-treatment procedures and susbtrate properties) are among the few that could affect the resultant polyamide physicochemical properties (i.e. its thickness, roughness, crosslinking %, etc). Of course, these are not the only factors involved as there is a WIDE range of parameters that could be controlled. TFC is mainly used in nanofiltration and RO due to its denser layers. Hope this helps and have fun researching/fabricating membranes !! 😁😁
