摘要: Two-dimensional heart-cutting gas chromatography is used to analyze dissolved hydrogen sulfide in crude samples. Liquid samples are separated first on an HP-PONA column, and the light sulfur gases heart-cut a GasPro where from other detected with chemiluminescence detector. Heart-cutting accomplished use of Deans switch. Backflushing columns after detection eliminates any problems caused by high-boiling hydrocarbons Dissolved quantified 14 oil samples, results shown this work. The method also applicable analysis headspace over Gas measurements compared liquid for same sample set. chromatographic system design discussed, chromatograms representative shown.
