Abstract
Temperature-programmed retention indices, relative to a homologous n-alkane series, were determined for twenty-two chemical warfare agents and simulants using fused-silica capillary columns coated with DB-1, DB-5, DB-1701 and DBWAX films. Reproducibility of retention indices, based on Van den Dool's equation, was excellent over the course of the study. The applicability of this method for compound verification was demonstrated by the analysis of a soil sample containing chemical warfare agents. In addition, an on-column injector of our own design was evaluated for use with wide bore fused-silica capillary columns.
