Two Dimensional Gas Chromatography- A Review

Abstract

The birth of two-dimensional gas chromatography is assumed to be the ninetieth year of the last century. Two-dimensional gas chromatography is a rapidly developing analytical technique. GCxGC is a truly hyphenated chromatographic technique which employs a pair of GC column. GCxGC analyses, such as the identification of trace compounds that would not be perceived by 1D-GC. The use of 2D-GC compared to that of 1D-GC has been discussed. The paper presents the introduction, principle of operation, working, uses, application, case studies has been discussed.
