Analysis of Chemical Warfare Agents and Their Related Compounds Using Gas Chromatograph with Atomic Emission Detector

Abstract

Gas chromatographic analysis with atomic emission detection (GC-AED) was performed for 17 chemical warfare agents (CWAs) and their 17 related compounds. Specific hetero elements in all CWAs and their related compounds were clearly detected, and their detection limits, linearity of their calibration curve, and within-day variability were evaluated. Some CWAs could be identified with respect to their peak area ratios of their hetero elements and their retention indices. GC-AED can be a powerful tool for screening CWAs in a complex matrix.
