毛细管柱样品容量很小,需要使用高灵敏度的检测器和小的死体积,所以,目前绝大部分的毛细管色谱分析都采用离子化检测器,其中以FID为最多。FID—毛细管柱系统不适合分析非烃类、惰性气体以及在火焰中难以电离或不电离的物质,对于FID,许多样品需要用一种溶剂来稀释,FID的定量校正因子不宜直接引用文献值,此外,在毛细管色谱应用较多的石油化工等单位都存在大量的易燃易爆气体,需严禁烟火,都比
Capillary samples are small in size and require the use of highly sensitive detectors and small dead volumes, so most of the current capillary chromatography uses ionization detectors, with FIDs as the most. FID-capillary column system is not suitable for analysis of non-hydrocarbon, inert gases and substances difficult to ionize or ionize in the flame. For FID, many samples need to be diluted with a solvent. FID quantitative correction factor should not be quoted directly, In addition, the capillary chromatography applications more petrochemical units exist a large number of flammable and explosive gases, fireworks are strictly prohibited, than the
