对应用棒状薄层色谱/氢火焰离子化检测器(TLC/FID)测定重油烃族组成(饱和烃、芳烃、胶质)时的影响因素作了探讨。研究发现,在点样及展开过程中,溶剂共挥发可引起样品损失;而且,由于TLC/FID的火焰温度远低于一般GC条件下FID的火焰温度,使不同化合物在FID上的燃烧转化情况有差异,因而其定量校正因子不具有通用性。

The influencing factors in the determination of hydrocarbons (saturates, aromatics, resins) in heavy oils by thin layer chromatography/flame ionization detection (TLC/FID) were investigated. It has been found that the solvent co -volatization may cause sample loss during the spotting and developing process, and that the quantitative calibration factors can not be used universally. Because the flame temperature of TLC/FLD is much lower than that of GC/FID, the transformation of different compounds in the flame of FID is varied.
