Applications of coupled LC‐GC: A review

Although coupled liquid chromatographygas chromatography (LC‐GC) was first demonstrated ten years ago, only in the last few years has there been a sudden surge of interest in the technique. Approximately 70% of the total number of LC‐GC applications have been published in the last two years (1987–88) alone. This review categorizes LC‐GC publications into four main application areas: fossil fuels, foods, environmental samples, biologiical/pharmaceutical samples, and miscellaneous samples. Multidimensional separations carried out using other coupled‐column chromatographic techniques (such as supercritical fluid chromatography (SFC) with GC, and on‐line trace enrichment‐GC) have also been included in this review.
