As a new technology, comprehensive two -dimensional gas chromatography( GC×GC)has many obvious advanta- ges in comparison with conventional gas chromatography, such as large peak capacity, high resolution, good sensitivity and high qualitative reliability. GC×GC will be more widely applied in the analysis of complex samples from petrochemical, tobacco, food and environmental industry. In this paper, the principle of GC×GC was introduced briefly. At the same time, this paper primari- ly focused on the applications of GC× GC in environment in the last decade and it mainly involves the applications in detection of organochlorine pesticides, polychlorinated biphenyls, polyaromatic hydrocarbon, dioxin and so on.
