High-speed gas chromatography: an overview of various concepts.

Journal of chromatography. A

Cramers CA, Janssen HG, van Deursen MM, Leclercq PA.
PMID: 10526794
J Chromatogr A. 1999 Sep 24;856(1):315-29. doi: 10.1016/s0021-9673(99)00227-7.

An overview is given of existing methods to minimise the analysis time in gas chromatography (GC) being the subject of many publications in the scientific literature. Packed and (multi-) capillary columns are compared with respect to their deployment in...

The use of a continuous slow injector for the production of calibration vapour mixtures in the parts per million by volume range.

Fast gas chromatography: packed column solvating gas chromatography versus open tubular column gas chromatography.

Journal of chromatography. A

Wu N, Medina JC, Lee ML.
PMID: 11045476
J Chromatogr A. 2000 Sep 15;892(1):3-13. doi: 10.1016/s0021-9673(00)00152-7.

Packed capillary column solvating gas chromatography (SGC) and open tubular column gas chromatography (GC) were compared with respect to their potentials for fast separations. A recently introduced "universal" peak capacity equation was used to compare the performance of these...

Efficiency through combining high-performance liquid chromatography and high resolution gas chromatography: progress 1995-1999.

Journal of chromatography. A

Grob K.
PMID: 11045501
J Chromatogr A. 2000 Sep 15;892(1):407-20. doi: 10.1016/s0021-9673(00)00048-0.

Progress during the last 5 years in on-line LC-GC and related techniques is reviewed. In normal-phase LC-GC, the wire interface proved to have advantages over the loop type interface. Further investigations on the solvent evaporation process in an uncoated...

Standardized test mixture for the characterization of comprehensive two-dimensional gas chromatography columns: the Phillips mix.

Journal of chromatography. A

Dimandja JM, Clouden GC, Colón I, Focant JF, Cabey WV, Parry RC.
PMID: 14650620
J Chromatogr A. 2003 Nov 26;1019(1):261-72. doi: 10.1016/j.chroma.2003.09.027.

A novel column characterization test mixture is developed for use in comprehensive two-dimensional gas chromatography (GC x GC). This mixture has been named the "Phillips mix" in honor of the late professor John B. Phillips, the father of GC...

Liquid-crystalline stationary phases for gas chromatography.

Journal of chromatography. A

Witkiewicz Z, Oszczudłowski J, Repelewicz M.
PMID: 15679153
J Chromatogr A. 2005 Jan 14;1062(2):155-74. doi: 10.1016/j.chroma.2004.11.042.

Physico-chemical properties of new liquid-crystalline stationary phases (LCSPs) for gas chromatography are reviewed. The mechanism of chromatographic separation on liquid-crystalline stationary phases is discussed and examples of analyses of complex mixtures of organic compounds using capillary and packed columns...

Increasing selectivity in comprehensive three-dimensional gas chromatography via an ionic liquid stationary phase column in one dimension.

Journal of chromatography. A

Siegler WC, Crank JA, Armstrong DW, Synovec RE.
PMID: 20356600
J Chromatogr A. 2010 Apr 30;1217(18):3144-9. doi: 10.1016/j.chroma.2010.02.082. Epub 2010 Mar 06.

Recent advances in improving the selectivity and performance for a comprehensive, three-dimensional (3D) gas chromatograph (GC(3)) instrument are described. With GC(3), two six-port diaphragm valves are utilized as the interfaces between three, in-series capillary columns housed in a standard...
