“…The GC×GC-TOFMS system may also be operated in the 1D mode by deactivating the thermal modulator. The functions of the thermal modulator have been described elsewhere [8,27,[31][32][33]. Data was continuously acquired by the high speed detector (TOFMS) 8 Chromatography Research International and deconvoluted by commercially available software (ChromaTOF), that came with the instrument, which generated contour plots, as well as three-dimensional chromatograms, based upon the user defined modulation period.…”

This research evaluates a recently developed comprehensive two-dimensional gas chromatography 2D GC coupled with a time-of-flight (TOF) mass spectrometer for the potential separation of 209 PCB congeners, using a sequence of 1D and 2D chromatographic modes. In two consecutive chromatographic runs, using a 40 m, Rtx-PCB column, and a 1 m DB-17 column, connected in series, 196 PCB congeners are distinguished, including 43 of the 46 pentachlorobiphenyl isomers. Some of the chlorinated biphenyls that could not be resolved chromatographically are resolved with the use of the "ortho effect," which distinguishes PCB isomers having 2,2 -; and 2,2 6-chlorine substitution from those isomers without these substitutions. The result of this work falls short of our goal of separating all 209 PCB congeners but still provides investigators with a new tool for a better front-end separation of PCB-specific congeners, and potentially, for use in acquisition of more accurate data.

“…A new analytical technique called comprehensive twodimensional gas chromatography (GC6GC) is capable of separating an order of magnitude more compounds from complex mixtures than traditional GC [62,63]. Increased chromatographic resolution is achieved by using two chromatographic columns with different selectivities coupled together by a modulator, commonly thermal [64 -66].…”

ReviewGas chromatography coupled to mass spectrometry for analyses of organic compounds and biomarkers as tracers for geological, environmental, and forensic research Gas chromatography, especially when coupled with mass spectrometry, is the analytical method of choice for elucidation of biomarker compounds present in organic mixtures extracted from geological, environmental, and biological samples. This review describes the biomarker concept, i. e., the precursor natural products to the geological/environmental derivatives, and their application as multi-tracers in the geosphere and ambient environment. The mass spectrometric methods currently utilized for such analyses are reviewed with a general key to the literature, and typical examples of applications using GC -MS are also described.

“…In comprehensive GC × GC, the sample is first separated on a high-resolution capillary column in a programmed temperature mode. Using a device called a thermal modulator (see Section 2.2), fractions of the effluent from this first column are focused at regular, short intervals and injected onto a second capillary column which is short and narrow to allow very rapid, isothermal separations [10][11][12].…”

“…Compared to conventional MDGC, the main advantages of comprehensive GC × GC are [10][11][12]: -A much higher peak capacity, which involves an improved separation of the trace components from other overlapping components. It provides optimal separation of complex mixtures into well-separated individual peaks (peak capacities of 30 000 and integration of more than 5000 peaks are currently achieved).…”

Résumé -Intérêt et applications de la chromatographie en phase gazeuse multidimensionnelle pour l'analyse des composés à l'état de trace dans l'industrie pétrolière -L'objectif de cet article est de démontrer l'intérêt et les avantages de la chromatographie en phase gazeuse multidimensionnelle (CPG MD) pour analyser des composés présents à l'état de trace dans des matrices organiques complexes comme les mélanges d'hydrocarbures, les échantillons d'huiles ou pétroliers et les charges et effluents des procédés pétrochimiques ou de raffinage. Dans ce cas, la réussite de l'analyse de trace dépend considérablement de l'étape de séparation et, à cet égard, la chromatographie en phase gazeuse multidimensionnelle peut fournir une augmentation de la capacité de pic permettant une meilleure identification et quantification des composants à l'état de trace. Des notions générales de l'analyse de trace organique dans le domaine de l'industrie pétrolière ainsi que le principe de la CPG MD et de la chromatographie en phase gazeuse bidimensionnelle (GC-2D) sont présentés. L'instrumentation est illustrée avec une attention particulière aux derniers développements de la CPG MD. Diverses applications de la CPG MD et de la GC-2D soulignent l'apport de ces techniques d'analyses comme la détermination des traces d'oxygénés dans la coupe C 4 par CPG MD ou la quantification et la détermination de sous-produits présents à l'état de trace dans des procédés pétrochimiques comme les procédés Fischer-tropsh ou de déhydrogénation de normales paraffines.
