Theory and development of coupled high performance liquid chromatography-gas chromatography
The couple of LC and GC has important applications in the aspects of pre-separation and enrichment,which effectively reduces the difficulty of sample preparation.Compared to other technologies,LC is more efficient in terms of separation power and can fully integrate sample preparation into GC.In this paper,the advantages of coupled HPLC-GC technology are discussed.The solvent evaporation and interface techniques of this technology are summarized.
