We have developed a high-performance liquid chromatographic method to determine aliphatic, polyfunctional amines at low levels in water, ammonia and other amines. This method is potentially valuable for determining trace &mine by-products in industrial samples, such as crude and refined piperazines.
The polyamines putrescine, cadaverine, spermidine, and spermine and the corresponding mono-N-acetylpolyamines can be separated as their dimethylaminoazobenzenesulfonyl derivatives in a single analysis in less than 22 min. The method employs reversed-phase high-performance liquid chromatography (Sphe
