Ion-chromatographic determination of the constant of ion exchange of aliphatic hydrazines and amines on silica-gel-based sulfocationites

Based on studies of the ion-chromatographic retention of 16 aliphatic amines and hydrazines on Diasorb-130-Sulfo and Nucleosil 5 SA, the relevant ion-exchange constants were calculated. The selectivities of the retention of these compounds were compared. The mass-spectrometry detection was used after the chromatography separation. The characteristics of the mass spectra of the aliphatic amines and hydrazines were discussed. Optimum conditions of detection were determined.
