摘要
报道了薄层色谱-氢火焰离子检测法在重质油的族组成分析中的应用。方法可有效分离和检测重质油的族组成(饱和烃、芳香烃、胶质等)。该方法具有快速、准确、样品及溶剂用量少等特点。在一定试验条件下,原油的种类和实际点样量不影响氢火焰离子检测的响应值。
The group-components (i. e. the saturated hydrocarbons, aromatic hydrocarbons and resins) were effectively and rapidly separated and determined by thin layer chromatography with hydrogen flame ionization detection. Only 0. 10 to 0. 12g of sample was needed and dissolved in 4. 00ml of toluene. A marketed chromatographic rod (S Ⅲ ) spreaded with silica-gel was used for the separation. One \A. of the sample solution was applied with a mi-crosyringe to the origin point of the chromatorod. After developing twice, the organic compounds were burned in the FID, and the ions captured by FID, and finally a chromatogram was obtained after amplification. This method was used for analysis of heavy oils with b. p. higher than 300℃. Different sorts of crude oils and the size of the applying spot do not influerce the FID responses, and the detector was feasible for the linearity in range of mass studied.
