I'm also doing some research right now on chemicals which could react with PFAS because if I find something interesting, I could make the PFAS in samples react with those chemicals and produce specific products which may be easier to discover through other technics... right? (For example, these...

Does anybody know anything about paper chromatography or about electrophoresis paper chromatography? Would these techniques be suitable for discovering PFAS molecules or not? (Always regarding air samples)

Thanks for the great explanation, I needed it. And I agree with you on the fact that seems not to be any other alternative than using the IR absorption spectrum of the C-F bond. Do you have any suggestions for this? (regarding also the things I said in the previous messages)

The example link you sent me seems quite good. I've been struggling to find such resources online, indeed the only ones I found that talk about sampling are in Italian and I thought they might be unhelpful for the thread. I'll keep up with the research on sampling technics starting from the...

Ok, thanks! I'll do some research on what you are suggesting and come back later.

So, you're saying that NIR spectroscopy of C-F bonds is actually possible? Do you have any documentation I could read? Thanks!

Other things I've been looking at are mass sensors like FID (flame Ionization Detector), PID (photoionization detector) and TED (thermal-electron-conductivity detector). I also found some electrochemical sensors like CWE (cantilever-based sensors) and LWE (laser-based sensors). Does anyone know...

I don't know exactly the concentration of PFAs, because I'll take the samples directly on situs and try to analyze those samples in the same system that took them. Even though, I think the concentration will be pretty low, so a system with relatively high sensitivity would be better.

These are some of the documents I've been reading: https://www.chimica-online.it/download/spettri_IR/interpretazione_spettri_IR.htm https://www.osti.gov/pages/servlets/purl/1779052 https://www.atsdr.cdc.gov/pfas/docs/PFAS_FamilyTree_EnvHealthPro-508.pdf...

Hi there, I'm working on a project where my aim is to detect the presence of PFAS (Per- and poly-fluoroalkyl substances) in air samples gathered by a system. I've done a ton of research, but most solutions are unachievable due to price and the available space (the system should be relatively...
