Rapid sequential heart-cut multidimensional gas chromatographic analysis.

Journal of chromatography. A

Dunn M, Shellie R, Morrison P, Marriott P.
PMID: 15595546
J Chromatogr A. 2004 Nov 12;1056(1):163-9. doi: 10.1016/j.chroma.2004.05.048.

A method is described which allows the sequential fast analysis of heart-cuts taken during the first column elution of an essential oil sample in a multidimensional gas chromatography experiment. In this investigation, a relatively short, narrow bore capillary column...

Properties of columns with several pyridinium and imidazolium ionic liquid stationary phases.

Journal of chromatography. A

Shashkov MV, Sidelnikov VN.
PMID: 23958690
J Chromatogr A. 2013 Sep 27;1309:56-63. doi: 10.1016/j.chroma.2013.08.030. Epub 2013 Aug 13.

Recent advances in the development of new liquid phases (ILs) made it possible to use some classes of ILs as polar stationary liquid phases (SLP). In our days only alkylimidazolium- and alkylphosphonium-based ILs are widely used as polar SLP....

Comprehensive two-dimensional gas chromatography with pattern modulation.

Journal of chromatography. A

Seeley JV, Seeley SK.
PMID: 26278359
J Chromatogr A. 2015 Nov 20;1421:114-22. doi: 10.1016/j.chroma.2015.07.117. Epub 2015 Aug 06.

Comprehensive two-dimensional gas chromatography (GC×GC) modulators normally transfer primary column effluent to the head of the secondary column as a series of sharp pulses. Such pulses are produced with time-varying temperature gradients in thermal modulation or with time-varying flow...

Coupling HPLC to GC: why? How? With what instrumentation?.

Journal of chromatographic science

Munari F, Grob K.
PMID: 2273062
J Chromatogr Sci. 1990 Feb;28(2):61-6. doi: 10.1093/chromsci/28.2.61.

Coupling LC to GC alleviates sample preparation in the sense of preseparation, cleanup, or enrichment and replaces conventional methods such as column liquid chromatography, enrichment by or filtration through sample preparation tubes, preparative thin-layer chromatography, or liquid-liquid partitioning. LC...
