TLC/FID方法的建立,主要根据现行沥青族组份分离过程中的某些局限性,采用薄层色谱(TLC)与氢火焰离子化检测器(FID)相结合,以硅胶或氧化铝吸附剂涂制于TLC烧结棒,点样和色谱展开,在棒架上以恒定的速度移动通过检测器火焰,各组份被自动扫描。该方法简便快速准确,几乎适应于所有低挥发有机化合物的分离分析,特别适用于沥青含量极低的碳酸盐岩样品的分析。
The establishment of the TLC / FID method is based on the limitations of the current separation of the asphaltene components. TLC and FID are combined with silica gel or alumina adsorbent Coated on TLC sintered rods, spotted and chromatographed, moving on a stick rack at a constant rate through the detector flame, the components are automatically scanned. The method, which is simple, rapid and accurate, is suitable for almost all the separation and analysis of low volatility organic compounds and is especially suitable for the analysis of carbonate samples with extremely low bitumen content.
