摘要：

The chromatographic behaviour of primary aliphatic amines on different capillary columns (OV-1, SB-phenyl-5 and SB-biphenyl-30) is described. The best performance was obtained using the OV-1 column; however, this column showed some peak tailing and losses probably due to adsorption effects. The primary amines heptylamine, undecylamine, tetradecylamine and stearylamine with K(b) almost-equal-to 4.10(-4) were eluted from the columns using both carbon dioxide and nitrous oxide as mobile phase, and no difference in chromatographic performance was observed using either mobile phase. The use of flame ionization detection using nitrous oxide as mobile phase is discussed.
