✦ Synopsis
Compliance with international treaties, destruction of stockpiled material, and possible terrorist use constitute a need to correctly identify and quantify Ž . chemical warfare CW agents and related materials. Gas chromatography, with any of a wide array of detectors, can be used to detect and quantify CW material.
Ž . The atomic emission detector AED uses a high temperature microwave induced plasma to atomize compounds eluted from the gas chromatograph. Atoms excited by the plasma give off characteristic spectral lines as they return to their ground state. The light is dispersed and detected with a spectrometer. The power of the AED lies in its ability to detect a wide range of elements. For chemical agents and related materials, the AED is used for sample screening, structure elucidation, and compound independent calibration. Examples of each of these areas will be discussed.
