Gas chromatographic retention indices for N-substituted amino s-triazines on capillary columns. Part V. Temperature dependence of the retention index

Abstract

The temperature dependence of the retention index was studied for N-substituted amino s-triazines on DB-1, DB-5 and DB-WAX capillary columns within the temperature range 190–230ºC. Two linear equations with the column temperature and its reciprocal as variables were studied. The first one shows a slightly better precision for 2,4-bis(alkylamino)-6-chloro-s-triazines and 2-alkylamino-4,6-dichloro-s-triazines, while the second one shows a better precision for 2,4-bis(cycloalkylamino)-6-chloro-s-triazines.
