An Experimental Gas Chromatographic C.W. Agent Detection Aparatus
Abstract
An experimental vapour detection apparatus has been devised consisting basically of a modified argon ionization detector, the anode of which serves also as a built-in miniature gas-liquid chromatographic column. Tests of the apparatus in the laboratory and in a gas chamber have shown that it is capable of detecting dangerous vapour concentrations of likely C.W. agents within a few seconds, even in the presence of innocuous vapours simulating likely atmospheric pollutants. The reasons leading to the detector design are given and followed by a description of the modified anode and the operation of the detector. The causes of drift and sensitivity limitations are examined, and simple schemes to eliminate them are described. The report concludes with a description of the experimental C.W. agent detection apparatus, and account of the experiments undertaken, and the results obtained investigating characteristics such as the sensitivity, speed and linearity of response. The results obtained are considered sufficiently encouraging to justify further investigation of the behaviour of an apparatus of this type in the natural atmosphere in a variety of environmental conditions, with emphasis on its possible development into a compact, automatic C.W. alarm for Service use.
