Answer 1

Answer:

Thin layer chromatography (TLC), or planar chromatography, began as a method of separating mixtures by eluting them through a planar chromatographic bed then visualising the separated components by staining or charring. In its simplest form TLC plates can be prepared in the laboratory, the plate placed in any suitably sized container and the resultant chromato-gram scanned visually. At its most sophisticated there is a large variety of plates, sample application aids including automated applicators, developing chambers, visualisation aids, scanning devices and adsorbents commercially available. TLC can be an excellent qualitative and quantitative method and more detailed descriptions of the techniques employed will follow.
