How do you measure PFAS in real time? Are there commercial instruments or DIY?

surrattairchemlab.bsky.social•73 days ago

CIMS

Thanks! Good luck to your team!

What are the major PFAS you see? Only gas phase or will you do some sort of aerosol volatilization?

surrattairchemlab.bsky.social•73 days ago

Sorry Paul forgot to say we have all of the instruments on a mobile platform

So mainly gas phase, but also collecting aerosols not with CIMS. Using AMS for realtime measure of organic F and high vols for offline characterization of particulate PFAS with LC or GC interfaced to ion mobility ultra high res tandem
MS.

We are mainly measuring GenX (and other PFECAs), PFCAs, FTOHs, HFO, vinyl ethers (PPVE, PMVE, PEVE), HFO, HFP, DFP, OFB and epoxides (HFPO). These are the ones in NC that are coming from a point source (Paul happy to tell you the point source offline as we don’t want them to know we are coming)

Good luck! Where are you sampling?
