A brief history and recent advances in ozone induced chemiluminescence detection for the determination of sulfur compounds by gas chromatography

Abstract

Ozone induced chemiluminescence is one of the most viable detection techniques for the chromatographic determination of ultra-trace sulfur compounds in difficult matrices.

Flow injection gas chromatography with sulfur chemiluminescence detection for the analysis of total sulfur in complex hydrocarbon matrixes

“…semivolatile sulfur-containing compounds in various matrices. A number of selective detectors, such as flame photometric detector (FPD) and its variants, sulfur chemiluminescence detector (SCD), atomic emission detector, and mass spectrometry detector have been applied successfully for the selective determination of sulfur compounds [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. As sulfur selective detectors, both SCD and FPD utilize the chemiluminescent reactions of sulfur compounds in a hydrogen/air flame to achieve selective and sensitive detection of these specific compounds.…”

“…FPD has its constraints including the lack of linearity in response due to formation of diatomic species S 2 and quenching or suppression of sulfur signal by coeluted hydrocarbons. Compared to FPD, SCD favorably produces a linear response, offers very high selectivity, and is far less susceptible to hydrocarbon interferences [6,10,11,[18][19][20][21][22].…”

“…In a recent review, the evolution, recent development of SCD, and the key applications of this technique have been discussed in detail . SCD is proved to be an excellent tool for sulfur compound analysis in hydrocarbon matrices.…”

“…SCD is proved to be an excellent tool for sulfur compound analysis in hydrocarbon matrices. By combining the separation power of an analytical column in capillary GC with this highly sensitive and selective detector, detailed speciation analysis of individual sulfur compounds can be achieved . Speciation is desirable but not always necessary.…”

“…As sample matrices become more complex and the needs for ultratrace analysis intensify, a reliable, rapid, low‐maintenance, and cost‐effective technique for total sulfur analysis is highly demanded in nearly all segments of the petroleum and chemical industry. SCD offers capability of rapid measurement of total sulfur without chromatographic separation, which has been showcased in the literature . The burner employed in this model, 8355 SCD is a redesigned and upgraded version of the original 2004 dual‐plasma design with substantial mechanical improvements, which render a platform that is more robust and reliable, easy to operate and maintain, and offers better sensitivity and selectivity .…”
