β¦ Synopsis
A method for the trace analysis of polyamines is presented. It involves permethylation of the amines to the corresponding tertiary amines, extraction of the latter into an organic solvent and subsequent analysis by gas-liquid chromatography using nitrogen-selective detection.
The chromatographic behaviour was considerably improved compared with direct analysis of underivatized polyamines, and gave detection limits of the order of 0.1 ng/pl and linear calibration plots in the 0.1-100 ng range. Amines of interest from work environmental health aspects were included as model compounds.
