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

Abstract

ReviewUnique selective detectors for gas chromatography: Nitrogen and sulfur chemiluminescence detectors Many of present day's complex analyses and challenging analytical tasks demand highly selective detection techniques for GC. Universal nitrogen/sulfur chemiluminescence detection is one of the most powerful analytical tools for gas chromatographic analysis. Its strength stems from the unique and beneficial characteristics of high selectivity, sensitivity, and equimolarity. The nitrogen/sulfur chemiluminescence detection technology has provided analytical solutions unsurpassed by any other techniques to a broad range of applications in petroleum characterization, food/beverage flavor analysis, and environmental monitoring. This paper presents a general review of this unique technology, including a brief description of operating principles, an overview of detector performance, practical discussions on instrument operation, and a sizable list of applications.

Small-Chamber Measurements of Chemical-Specific Emission Factors for Drywall

“…SCD is suited to identifying and discriminate among extremely low concentrations of sulfur components (Yan, 2006); and SPME has been found to be effective in identifying VSCs in air (Ras et al, 2008b;Shirey, 1997). Both methods were used to quantify VSCs, as described in the results and discussion section.…”

“…The SCD has a number of advantages for sulfur gas analysis over other detectors, including a wide linear range and equimolar response for all sulfur compounds, plus very good sensitivity and selectivity (Hua et.al., 2004;Yan, 2006;Pandey and Kim, 2009). The equimolar response allows for the quantification of all analytes in the sample, even unknowns, based on a single standard calibration.…”

Assessment of SCD-DP calibration to quantify traces of sulfur compounds in gaseous streams

“…Identification and quantification of sulfur compounds require a suitable analytical procedure (Yan, 2006;Miller and Bruno, 2003). Gas chromatography (GC) is a very powerful technique to identify and quantify sulfur compounds present in gaseous streams.…”

“…Extensive reviews of sulfur chemiluminescence detectors (SCD) for gas chromatography have been published (Gras et al, 2005;Yan, 1999Yan, , 2002Yan, , 2006Johansen et al, 2005). There are relatively few reports on the use of SCD with dual plasma (DP) systems for analysis of sulfur compounds in gaseous streams from refineries (Gras et al, 2005).…”

“…The first one has two advantages: (i) the detector response is more stable, and (ii) it presents an excellent, accurate analysis at μg.m -3 levels for light sulfur compounds. Comprehensive two-dimensional gas chromatography coupled with fast sulphurchemiluminescence detection appears to be a useful technique to analyze liquid petroleum products (Blomberg et al, 2004, Yan, 2006, but apparently no studies using refinery gaseous streams have been reported.…”
