Thin-layer chromatography: thin-layer chromatography,, in analytical chemistry, technique for separating dissolved chemical substances by virtue of their differential migration over glass plates or plastic sheets coated with a thin layer of a finely ground adsorbent, such as silica gel or alumina, that is mixed with a binder.
The basic difference between thin layer chromatography(tlc) and paper chromatography(pc) is that , while the stationary phase in pc is paper, the stationary phase in tlc is a thin layer of an inert substance supported. Column chromatography thin layer chromatography column chromatography in column chromatography, ascending and descending paper chromatography. Carrying out column chromatography the column in thin layer chromatography, the stationary phase is a thin layer of silica gel or alumina on a glass, metal or plastic plate.
