Quantification of 23 Volatile Organic Compounds with a Single Reference Material Using Post-column Reaction Gas Chromatography Combined with a Stainless-steel Heating Furnace

We built a heating furnace using stainless-steel instead of aluminum in gas chromatography combined with an oxidation/ reduction system; it increased the oxidation temperature to 650°C. At 600°C, it completely oxidized five organochlorine compounds. This system was applied to a standard solution of 23 volatile organic compounds. The analytical results of 20 hydrocarbon and organochlorine compounds showed good agreement with the expanded uncertainty ( k = 2) of the reference values. Three organobromine compounds obtained values higher than the reference; this was investigated further.
