Hi,

For the development of our PFAS method we are looking for some hard(er) to find analytical standards:

Native standards of the following compounds:

- PFPeDA (perfluoropentadecanoic acid)
- MeFBSAA (N-methyl perfluorobutane sulfonamido acetic acid)


Mass-labeled standards of the following compounds:

- ADONA (4.8-dioxa-3H-perfluorononanoate)
- PFECHS (Perfluoroethylcyclohexane sulfonate)

- PFTrDA (perfluorotridecanoic acid)
- PFPeDA (perfluoropentadecanoic acid)
- PFODA (perfluorooctadecanoic acid)

- PFPeS (perfluoropentane sulfonic acid)
- PFHpS (perfluoroheptane sulfonic acid)
- PFNS (perfluorononane sulfonic acid)
- PFDS (perfluorodecane sulfonic acid)
- PFUnDS (perfluoroundecane sulfonic acid)
- PFDoDS (perfluorododecane sulfonic acid)
- PFTrDS (perfluorotridecane sulfonic acid)

- PFBSA (Perfluorobutylsulphonamide)
- MePFBSA (Methyl-Perfluorobutylsulphonamide)
- MePFBSAA (N-methyl perfluorobutane sulfonamido acetic acid)
- PFHxSA (Perfluorohexanesulfonamide)
- PFOSAA (perfluorooctane sulfonamidoacetic acid)
- 6:2 PAP (Mono[2-(perfluorohexyl)ethyl] Phosphate)
- 8:2 PAP (Mono[2-(perfluorooctyl)ethyl] Phosphate)

I've already checked Wellington and Cambridge Isotopes.
Any advise would be much appreciated.

I worry that an ever expanding target list + isotope dilution + part per quadrillion reporting levels are going to make these analyses too expensive for general use.

It already requires pretty much the top end instruments from the manufacturers and the standards are very expensive. I think EPA is beginning to work on methods that don't require a labeled version for every single target, but it is still going to be expensive.
The past is there to guide us into the future, not to dwell in.

I agree, but for now 'the gap' in my labeled standards is just to big so I'm looking for some extra components. Depending on the availabilty and the price I can than make a selection.
