Screening of degradation products, impurities and precursors of chemical warfare agents in water and wet or dry organic liquid samples by in-sorbent tube silylation followed by thermal desorption–gas chromatography–mass spectrometry
چکیده انگلیسی

A standard method used by inspection teams of the Organisation for the Prohibition of Chemical Weapons (OPCW) for preparation of aqueous samples requires several extraction and derivatization steps. This results in tedious and time consuming on-site analysis. A simple thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) method was developed to analyse for a broad range of degradation products, impurities and precursors of chemical warfare agents (CWA) in water solutions and wet or dry organic liquid samples. The method is fast, sensitive, requires only microliter volumes of sample and enables the simultaneous determination of a wide range of compounds with widely differing polarity, volatility and reactivity. The applicability of the method was demonstrated by successful analysis of five OPCW Official Proficiency Test samples.
