Here are some tips for troubleshooting thin layer chromatography. The technique of thin layer chromatography (tlc) is normally used as an analytical method to follow the progress of a reaction, to analyse mixtures or to establish conditions for a preparative separation of compounds using column chromatography the stationary phase (often silica) is coated on plastic or aluminium. Discover the history of thin-layer chromatography: from its invention to major developments like hptlc, pre-coated plates, and tlc-ms coupling.
Thin-layer chromatography (tlc) is a simple, flexible and cost efficient separation technique for both qualitative and quantitative analysis, enabling simultaneous analysis of many substances with minimal time requirement tlc can be performed manually in easy and inexpensive ways therefore it is found in almost all.
