Abstract: A sensitive gas chromatography-mass spectrometry (GC-MS) based analytical method was developed for detection of the chemical warfare agents (CWA) and related compounds in air/vapor samples. The method uses a Tenax TA packed GC liner as an air/vapor sampling tube and Programmable Temperature-Vaporization (PTV) GC inlet as the thermal desorber. This approach eliminates secondary focusing step and allows transfer of desorbed analytes as sharp bands directly to the head of GC column. Use of a Peltier element for r…
