Gas-liquid chromatography (GIC) is one of most effective and widely applied methods for the separation, identification and quantitative analysis of complex multi-component mixtures. It has the advantages of high separation efficiency, considerably exceeding the possibilities of liquid chromatography (thin-layer chromatography (TIC), high-resolution liquid chromatography (HRIC)); good reproducibility of GIC chromatography parameters, facilitating identification and acquisition of precise quantitative results; high sensitivity; universality of the applied detection techniques, making it possible to identify with a low detection limit all classes of organic compounds; lasting quality of analytic columns (compared to that of BRIG) used in GIC for separation (up to two years of continuous work).
