Abstract
Gas chromatographic mass-spectrometric analysis was performed for chemical warfare agents and related compounds including sarin, soman, tabun, VX, mustard gas, lewisite 1, 2-chloroacetophenone, o-chlorobenzilidenemalononitrile and capsaicin, under electron ionization and methane chemical ionization conditions using apolar and polar capillary columns. It was possible to identify the tested compounds with respects to their retention indices and mass spectra. Under the analytical conditions of split ratio (50:1), electron ionization and scan mode data aquisition, the limit of detection ranged from 0.06 to 7 μg/ml, except for the low detection sensitivity of lewisite 1.
