Abstract The normal phase and reverse phase liquid chromatographic properties of seven 8-quinolinesulfonyl derivatives of primary and secondary amines are examined using dual wavelength ultraviolet detection. The amines are further identified by infrared spectrophotometry with emphasis on structural elucidation based on absorption bands at characteristic wavelengths.

Abstract An analytical method is described for the determination of mono- and dialkylamines in foodstuffs. Amines are derivatized to their pentafluorobenzamides which may be separated by gas chromatography (GC) and determined using an N-P detector. Analysis of the derivatives by GC-mass spectrometry indicated they were all mono-substituted. The amines were isolated from foodstuffs by alkaline distillation of ≥75% sample volume. The distribution of dimethylamine (DMA) in distillate volumes indicated 2 maxima from barley and malt, which could represent 2 or more sources of DMA. DMA concentrations of 6.6-8.8 ppm in barley, 11 ppm in malt, and 1.2 ppm in beer are higher than previously reported.

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.
