What is Trace Analysis of Organic Compounds in Volatile Inorganic Halides by the Dynamic Headspace Technique and Gas Chromatography—mass Spectrometry about?
The volatile chlorides of elements of Groups III-V are widely used in the preparation of ultra-pure materials for the electronics industry. SiC14, POCls, GeC14, BBrs and BCls of the highest purity with respect to trace transition elements and -H and -OH molecular impurities are used for the production of optical waveguide glass compositions. The presence of hydrogen-bearing organic and organohalogen impurities in the reactants leads to the undesirable formation of OH groups in fibre-glass during vapour phase oxidation. One of the most suitable methods for the analysis of volatile halides for organic impurities is gas chromatography (GC)'. The main problems in the direct GC trace analysis of readily hydrolysable and highly reactive substances, which include most volatile inorganic halides, are the choice of an appropriate liquid stationary phase2, the low detection limit of the detectors3 and overloading of the chromatographic column with the matrix substance. Closed-loop stripping analysis has been successfully applied to the determination of a wide range of volatile organic compounds from a variety of aqueous samples4. This pre-concentration technique, capable of achieving concent
