气相色谱中目前常用的 WCOT和 SCOT毛细管柱,一般是将预先选定的化合物均匀涂渍在毛细管内壁作为固定相,涂渍前后固定相的化学结构和形态没有变化。化学键合和交联型毛细管柱却不同,前者是固定相和玻璃表面的活性基团之间通过键合反应连成一体;后者是利用引发剂等使固定相高分
The commonly used WCOT and SCOT capillary columns in gas chromatography are generally uniformly coated on the inner wall of capillary tube as the stationary phase, and the chemical structure and morphology of the stationary phase before and after coating are unchanged. Chemically bonded and cross-linked capillary column is different, the former is the stationary phase and the glass surface of the active groups through the bonding reaction into one; the latter is the use of initiator to make the stationary phase score
