Use of equations for the description of experimental dependence of the height equivalent to a theoretical plate on carrier gas velocity in capillary gas-liquid chromatography.

Journal of chromatography. A

Berezkin VG, Malyukova IV, Avoce DS.
PMID: 10749492
J Chromatogr A. 2000 Mar 03;872(1):111-8. doi: 10.1016/s0021-9673(99)01275-3.

Optimal equation for fitting the experimental data on the height equivalent to a theoretical plate (HETP) versus carrier gas velocity in GLC was determined. The data obtained by authors and the literary data by other investigators were used for...

Comprehensive two-dimensional gas chromatography: metrics, potentials, limits.

Journal of chromatography. A

Blumberg LM.
PMID: 12580467
J Chromatogr A. 2003 Jan 24;985(1):29-38. doi: 10.1016/s0021-9673(02)01416-4.

Metrics for evaluation of separation performance of comprehensive two-dimensional gas chromatography (GCxGC) and for quantitative comparison of that performance with similar performance of its 1D (one-dimensional) counterparts are described. The performance improvement can be expressed via reduction in the...

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...

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...

Trends and developments in gas chromatography. Foreword.

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...

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...

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...

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...
