Medição de H<sub> 2</sub> S em Crude Oil and Crude Oil Headspace Usando Cromatografia Gasosa Multidimensional, Deans Comutação e Detecção de Enxofre-seletivo
A multidimensional gas chromatography method for the analysis of dissolved hydrogen sulfide in liquid crude oil samples is presented. A Deans switch is used to heart-cut light sulfur gases for separation on a secondary column and detection on a sulfur chemiluminescence detector.
