高效液相色谱—气相色谱联用(HPLC—GC)可望成为一项重要技术,用于分析那些在进行GC前需要预处理的样品。HPLC是一种很好的样品预处理方法,并且能与GC联用。对较大体积的流分(一般为100～1000μl)可采用溶剂汽化技术转输,下面将谈到两种HPLC—GC接口;本文还要对几种精选过的具有广泛实用性的HPLC—GC方法进行简介。HPLC—GC联用作为一个分析过程的最后一步,HPLC和毛细管GC是有效且完全可靠的。然而样品预处理通常仍然应用相当原始的方法,如液—液分配技术和常规的LC柱色谱(样品处理管)或薄层制备技术;上述方法分离效能
High Performance Liquid Chromatography-Gas Chromatography (HPLC-GC) is expected to be an important technique for analyzing samples that require pretreatment prior to GC. HPLC is a good sample preparation method and can be used with GC. For larger volume fraction (typically 100 ~ 1000μl) can be solvent vaporization technology transfer, the following will talk about two kinds of HPLC-GC interface; this article also on the selection of a wide range of practical HPLC- GC method for introduction. HPLC-GC As the last step in an analytical process, HPLC and capillary GC are effective and completely reliable. However, sample pretreatment usually still uses quite primitive methods, such as liquid-liquid dispensing techniques and conventional LC column chromatography (sample processing tubes) or thin layer preparation techniques; the above method separates performance
