摘要：

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 (MSn) using an ion trap SIMS. C2H5SC2H4+ from GEES eliminates C2H4 and H2S, which are highly diagnostic. GEES 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 m(2) g(-1). A single analysis could be conducted using only 2 mg of soil in under 5 min. (C) 1998 Elsevier;Science B.V. All rights reserved.
