摘要：

A gas-liquid chromatographic method for the determination of the triazines cyanuric acid, ammelide, ammeline and melamine at the nanogram level, using trifluoroacetic acid as solvent for the triazines and N-methyl-N-trimethylsilyltrifluoro-acetamide as the silylation reagent, is described. Optimal derivatization and chromatographic conditions have been determined. The relative molar response with respect to phenanthrene as the internal standard was found to remain constant for amounts of sample in the range 0.025-10 μg and the minimum detectable amount for quantitative analyses was found to be 2.5 ng (ca. 20 pmole) of each triazine. © 1979.
