薄层色谱(Thin-Layer Chromatography: TLC)是在玻璃板上,塑料片或者铝箔覆盖有很薄的一层吸附剂的一种用于分离混合物的色谱法。 薄层板展开的方法是其中一端被溶剂浸润后,溶剂在吸附剂的间隙中扩散,溶剂往上方移动进行爬板(毛细管现象)。如果在板子上点样混合物的话,那么化合物也会随着溶剂的移动而移动。这个时候...
3.2.1Thin Layer Chromatography (TLC) TLC is one of the modest and versatile techniques, used to obtain information about the adulterants, particularly artificial dyes present in Saffron. In this technique, separation of various compounds is achieved on TLC plates having layer of stationa...
The meaning of THIN-LAYER CHROMATOGRAPHY is chromatography in which a liquid sample migrates by capillarity through a solid adsorbent medium (such as alumina or silica gel) which is arranged as a thin layer on a rigid support (such as a glass plate).
High-performance thin-layer chromatography (HPTLC) is employed widely in pharmaceutical industries for process development, identification, and detection of adulterants in herbal products; identification of pesticide content and mycotoxins; and in quality control of herbs and health food. HP...
