Measurements of hydrogen sulfide (H<sub>2</sub>S) using PTR-MS: calibration, humidity dependence, inter-comparison and results from field studies in an oil and gas production region

“…These instruments have relatively poor detection limits (> 1 ppm) and are insufficient to detect H 2 S at ambient levels (Benner and Stedman, 1990). Chemiluminescence instruments based on reaction with ClO 2 (Spurlin and Yeung, 1982), O 3 (Kelly et al, 1983) and excited SO (Benner and Stedman, 1989) have a detection limit of 130 pptv for H 2 S, but there exist potential interferences from other hydrocarbons in environments like oil fields. Other commonly used instruments are based on cavity ring-down spectroscopy (CRDS) and gas chromatography coupled with isotope dilution mass spectrometry (Bandy et al, 1985) and sulfur chemiluminescence detection (GC-SCD) (Khan et al, 2012).…”

Unique selective detectors for gas chromatography: Nitrogen and sulfur chemiluminescence detectors

“…Empirical experimentation has established that reduction by hydrogen following oxidative combustion is required to produce the sulfur chemiluminescent species in SCD. This species has been widely believed to be sulfur monoxide (SO) [28], although serious questions about its identification remain [17,29]. Readers are referred to the cited references for more detailed discussions on this topic.…”

“…Researchers and manufacturers have come up with a number of designs over the years in search of a more efficient and stable SCD pyrolyzer. A hydrogen flame burner with a sampling tube was employed as the pyrolyzer in the original design of the flame-based SCD by Benner and Stedman [28]. The basic design was adopted in the first commercial instrument and interfaced with an existing FID on the GC (see Fig.…”

Role of GC in petroleum industry and petrochemistry. From hydrocarbon quantitative analysis to simulated distillation (in French).

“…Pour l'analyse des hydrocarbures gazeux, l'étape la plus importante a été le remplacement des colonnes remplies par des colonnes capillaires à film d'adsorbant, beaucoup plus efficaces et stables [1]. Quant aux détecteurs spécifiques, à côté de l'amélioration de la sensibilité et de la stabilité des principaux (photométrie de flamme et capture d'électrons), sont apparus ces dernières années deux nouveaux détecteurs beaucoup plus sensibles et quantitatifs : l'émission atomique [2,3] et la chimie luminescence [4].…”
