Rapid screening of aqueous chemical warfare agent degradation products: ambient pressure ion mobility mass spectrometry.

摘要: The use of electrospray ionization ambient pressure ion mobility spectrometry with an orthogonal reflector time-of-flight mass spectrometer to analyze chemical warfare (CW) degradation products from aqueous environmental samples has been demonstrated. Certified reference materials analytical standards for the detection Schedule 1, 2, or 3 toxic chemicals their precursors as defined by convention treaty verification were used in this study. A combination six G/V-type nerve and four S-type vesicant related CW agent separated baseline resolution instrumental technique. Analytical figures merit each product determined. In some cases, reduced constants (Ko) have reported first time. Linear response ranges selected found be generally ∼2 orders magnitude, where overall dynamic extend 4 magnitude. Limits o...
