The technique of trapping aliphatic amines from gaseous and liquid phases on solid polymeric organic sorbents followed by thermal desorption and quantitation by gas chromatography or, after conversion to fluorescent (UV) derivatives, by liquid chromatography was studied. The interaction of 8 primary aliphatic amines and 4 secondary amines with 3 sorbents, viz. Tenax GC, Chromosorb 103, and Separon SE, was examined. Analytical GC and HPLC procedures were developed for butylamine and subsequently tested on a C4 - C7 primary alkylamine mixture.
