Analytical Chemistry, 1998
This review of the fundamental developments in gas chromatography (GC) includes articles published from 1996 and 1997 and an occasional citation prior to 1996. The literature was reviewed principally using CA Selects for Gas Chromatography from Chemical Abstracts Service, and some significant articles from late 1997 may be missing from the review.

Multidimensionality in gas chromatography
TrAC Trends in Analytical Chemistry, 1996Many analytical problems require more resolution than a single chromatographic technique can provide. In such cases the separation power can be enhanced by using more than one separation technique or mechanism. The sample is then dispersed in different time dimensions.

Gas chromatography of flavonoids
Journal of Chromatography A, 1973Abstract The gas chromatography of some trimethylsilyl ethers of flavonoids and glycosides was carried out using the OV series of silicone polymers as liquid phases, and useful correlations between the Kovats retention indices and the substituents in flavonoids in some crude drugs by temperature-programmed gas chromatography were devised.

Science, 1967
Continuous gas chromatography has been achieved with a radial-flow chromatographic channel free of packing and formed between two closely spaced (50 to 75 microns) disc surfaces (optically flat and solvent-coated) rotating at one-half or one revolution per second. This technique provides high capacity and immediate response (in a fraction of a second).

Overview All forms of chromatography separate components of a mixture by taking advantage of the fact that each component has a different affinity for a particular media. Both liquid and gas chromatographs use this principle and employ two different media—a sorbent-packed column and a solvent (termed the stationary phase and the mobile phase)—to ...
