Live tests and real-time detection of CWAs
The nine most important CWAs (including Sarin, Tabun, Soman, VX, Lewisite, Cyclosarin, Nitrogen mustard and Sulfur mustard) have been investigated at a facility specialized and licensed for CWA handling.
H4+ turned out to be the perfect reagent ion for extremely sensitive and selective detection of most tested CWAs. Limits-of-Detection (LODs) in the gas phase were between 10 and 30 pptv for 1s integration time, i.e. for real-time analysis. Fast switching from H3O+ to NH4+ and back with SRI technology allowed to cover all CWAs of interest without delays. Surface contaminations of 1 ng/cm² could be easily detected for most compounds. Thus, a promising application in the security realm is decontamination control.
