That's a nice project! Of course, GCMS and LCMS need expensive laboratory equipment... Are you in touch with someone in this regard?

@christian_zerfass Nope. No contact yet. Any ideas?
And we're trying to find ways to do frugal analysis (I will ask in Frugal Science program from Prakash Lab)

@XavCC

I am not familiar with frugal analysis...

You are in Rennes, n'est-ce pas? Here is a link to a metabolomics publication incl. researchers from Rennes. The corresponding author's email is stated. Maybe they'd help as an outreach / citizen science support activity? They wrote about LCMS, which is equally feasible and currently our method of choice.

@christian_zerfass
Yep, I am.
Well done (^_~), And thanks for this nice resources for the weekend

@XavCC

Let me know if I can be if any further help 👍 it's an interesting project you are setting up!

@christian_zerfass Random question but related with our works (microfluidics for soil and water analysis)

If i'm right, Poly(dimethylsiloxane) is used as an anti-lice shampoo.

So, If we want to make "frugal" Poly(dimethylsiloxane)-Based Microfluidic Devices can we use this shampoo as a basis for our preparation?

@XavCC

I would assume no. To cast a device, you need to somehow polymerize / crosslink the PDMS. So you would have to purify, then test how to process to get a structural integrity - not sure that would work with the kind of PDMS used in shampoo, but I guess it is an additive of defined polymerization.

But I'm no expert on microfluidics..

Here's a webpage that may be useful for you:

@XavCC

P.S. There is a fablab in Rennes.. They may provide access to machines for projects like yours, to help e.g. with the microfluidics preparation
