Abstract

AbstractVarious gas chromatographic methods, which are useful for the screening of chemical weapons convention (CWC)‐related chemicals, are described in this article. The choice of columns, detectors, and injection techniques, crucial to the optimization of gas chromatography (GC) as a routine screening tool, is discussed. In addition, various screening and identification methods are described. The use of retention indices (RI) method allowing the identification without the need for an authentic chemical is described in detail. RIs are used as identification method also together with electron impact mass spectrometry (EIMS) in on‐site analysis method established by Organization for Prohibition of Chemical Weapons (OPCW).
