Investigation of the sulfur speciation in petroleum products by capillary gas chromatography with ICP-collision cell-MS detection

Investigation into the determination of trimethylarsine in natural gas and its partitioning into gas and condensate phases using (cryotrapping)/gas chromatography coupled to inductively coupled plasma mass spectrometry and liquid/solid sorption techniques

“…Along with the organic constituents, water can be present, as well as a variety of gaseous trace components as e.g. H 2 S. The typical composition of natural gas and its trace constituents can be found in a report by Attari and Chao [5], while the typical condensate constituents are shown in [4].…”

“…Trimethylarsine (TMAs) was found to be the major volatile arsenic species, contributing for 55-80% of the total volatile arsenic in this natural gas, besides mixed methyl-ethyl-trialkyarsines and triethylarsine. It was not until almost 10 years later that a scientific paper was published by Bouyssiere et al [4] on the identification of trialkylarsines in natural gas condensates. The major compound here was found to be triphenylarsine (TPhAs) along with triethylarsine and other, not further identified species.…”

Development of novel and sensitive methods for the determination of sulfide in aqueous samples by hydrogen sulfide generation-inductively coupled plasma-atomic emission spectroscopy

“…Although, inductively coupled plasma-mass spectrometry (ICP-MS) has been used for the determination of sulfur, it is well known that polyatomic oxygen ions greatly interfere with sulfur isotopes. These spectroscopic interferences can be avoided by desolvation, the introduction of a reaction-collision cell or a combination of both [26][27][28][29][30] as well by as the use of high resolution ICP-MS [31]. On the other hand, inductively coupled plasma-atomic emission spectroscopy (ICP-AES) has also been used for the determination of elementary sulfur [32,33].…”

A Review of Kinetic Modeling Methodologies for Complex Processes

“…As the GC technique is a separation technique but not an identification method, the chromatography column must be coupled to a specific detector. The most common detectors are: -Flame Ionization Detector (FID) (Adam et al, 2008;ASTM D6730, 2007;Johansen et al, 1983;Vendeuvre et al, 2005), -Sulfur or Nitrogen Chemiluminescence Detector (SCD/ NCD) (Adam et al, 2009;Dzidic et al, 1988;López García et al, 2002Revellin et al, 2005;Tuan et al, 1995), -Atomic Emission Detector (AED) (Andersson and Sielex, 1996;Depauw and Froment, 1997), -mass spectrometer (Bouyssiere et al, 2004;López García et al, 2002;Teng and Williams, 1994). GC techniques have a high separation efficient, equivalent to 2.5 10 5 theoretical plates, which allows them to identify up to 200 compounds in a mixture (Mondello et al, 2002).…”
