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. Thin layer chromatography (tlc) and column chromatography mprasad naidu msc medical biochemistry, phd. Chromatography is a technique used to separate mixtures into components as a result of differential partitioning behavior between a stationary phase and a mobile phase that percolates through the stationary bed.
Thin layer chromatography is another chromatographic technique used mainly to separate organic compounds as in other methods this also has the two phases known as mobile phase and stationary phase. Some of the advantages of thin layer chromatography (tlc) are as follows:-less equipment is required very little time for separation is required.Download
