I try to do epichlorohydrine at the purge and trap /GC-MS. Do you know Quantitation Ion of Epichlorohydrine? I could not find it.

The ion with the most abundance in the EI-spectra of epichlorohydrine is m/z = 57 ! If you don't have problems with background (tert. butyl-groups !!!) you should take this ion for quantitation ! The other ions in the EI-spectra of epi.... are of too low abundance, so you would probably get problems with LOD !
