Various gas chromatographic methods, which are useful for the screening of Chemical Weapons Convention (CWC)‐related chemicals, are described in this section. Choice of columns, detectors, and injection techniques, crucial to the optimization of gas chromatography (GC) as a routine screening tool, are discussed. Also, various identification methods are described. The use of the retention indices (RIs) method allowing identification without the need for an authentic chemical is described in detail. RIs are used as an identification method together with electron ionization mass spectrometry (EIMS) in the on‐site analysis method established by the Organization for the Prohibition of Chemical Weapons (OPCW).

“…Efficient quantitative analysis of complex mixtures containing hundreds or even thousands of organic compounds remains a prominent analytical chemistry challenge for the 21st century . Of special interest are organic mixtures rich in heteroatoms, including oxygen, sulfur, and nitrogen, which are more difficult to separate and detect by conventional gas chromatography techniques . Conventional detection of eluting compounds by flame ionization detection (FID) is significantly limited in quantifying chemicals with heteroatoms; for example, some oxygenates such as formaldehyde or formic acid are almost undetectable .…”

Quantitative analysis of complex mixtures containing hundreds-to-thousands of organic compounds rich in heteroatoms, including oxygen, sulfur, and nitrogen, is a major challenge in the fuel, food, and chemical industries. In this work, a two-stage (oxidation and methanation) catalytic process in a 3-D-printed metal microreactor was evaluated for its capability to convert sulfur-containing organic compounds to methane. The microreactor was inserted into a gas chromatograph between the capillary column and flame ionization detector. Catalytic conversion of all sulfur-containing analytes to methane enabled carbon quantification without calibration, by the method identified as "quantitative carbon detection" or QCD. Quantification of tetrahydrothiophene, dimethyl sulfoxide, diethyl sulfide, and thiophene indicated complete conversion to methane at 4508C. Long-term performance of a commercial microreactor was evaluated for 2000 consecutive injections of sulfur-containing organic analytes. The sulfur processing capacity of the microreactor was identified experimentally, after which reduced conversion to methane was observed.

“…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.…”

A fast and reliable analytical technique for the determination of total sulfur levels in complex hydrocarbon matrices is introduced. The method employed flow injection technique using a gas chromatograph as a sample introduction device and a gas phase dual-plasma sulfur chemiluminescence detector for sulfur quantification. Using the technique described, total sulfur measurement in challenging hydrocarbon matrices can be achieved in less than 10 s with sample-to-sample time <2 min. The high degree of selectivity and sensitivity toward sulfur compounds of the detector offers the ability to measure low sulfur levels with a detection limit in the range of 20 ppb w/w S. The equimolar response characteristic of the detector allows the quantitation of unknown sulfur compounds and simplifies the calibration process. Response is linear over a concentration range of five orders of magnitude, with a high degree of repeatability. The detector's lack of response to hydrocarbons enables direct analysis without the need for time-consuming sample preparation and chromatographic separation processes. This flow injection-based sulfur chemiluminescence detection technique is ideal for fast analysis or trace sulfur analysis.
