摘要
建立了快速测定重质油族组成的薄层色谱/氢火焰检测(TLC/FID)法。用两种展开剂可将试样很好地分成饱和烃、芳烃和胶质三个组分。本方法与液-固色谱法有较好的对应关系。标准偏差小于2m%,每分析10个样品只需2h,比液-固色谱法的分析时间大为缩短。
A rapid method for analyzing the hydrocarbon type of heavy oils by thin-layer chromatography(TLC)with flame ionization detection(FID)was investiga-ted.Satisfactary separation of saturates,aromatics and resins could be achievedby means of duel developing solvent.The standard deviation of TLC/FID me-thod was less than 2%(wt).The time required by this method for an'alysing 10samples was about 2 hours,much shorter than that usually required by liquid-solid chromatography method.
