Non-traditional agent/dusty agent detection system

摘要

A chemical agent detection system is described. The system comprises a sample introduction module, an agent concentration module and a detection module. The sample introduction module comprises a sample collector that collects particles and aerosols from a sample, and a heater that vaporizes the collected particles and aerosols and produces a sample vapor. The agent concentration module comprises a sorbent tube filled with a sorbent material that preferentially absorbs the vapor of a target chemical agent when the sample vapor passes through the sorbent tube. The detection module interrogates the sorbent material and identifies the target chemical agent absorbed to the sorbent material. Also disclosed are methods for detecting a non-traditional agent (NTA) or a dusty agent (DA), and trace levels of chemical warfare agents (CWA) and toxic industrial chemical (TIC) vapors.
