Abstract

2-Chloroethylethyl sulfide (CEES) is used as a simulant for mustard (HD) in a study to develop secondary ion mass spectrometry (SIMS) for rapid, semi- quantitative detection of mustard on soil. Selectivity and sensitivity are markedly improved employing multiple-stage mass spectrometry (MS(n)) using an ion trap SIMS. C2H5SC2H4/+ from CEES eliminates C2H4 and H2S, which are highly diagnostic. CEES was detectable at 0.0012 monolayer on soil. This corresponds to approximately 15 ppm (mass/mass) for a soil having a surface area of 12 m2 g-1. A single analysis could be conducted using only 2 mg of soil in under 5 min.
