Tutorial: Paper & Thin Layer Chromatography

The video tutorial explains chromatography, a technique used in forensic science to separate components of a mixture. It demonstrates the process using food coloring and chromatography paper, highlighting the roles of stationary and mobile phases. The concept of retention factor (RF) is introduced, explaining how it indicates the solubility of components. Thin layer chromatography (TLC) is also discussed, using a glass plate with a silica gel layer. The video concludes with applications of chromatography in identifying substances like drugs and inks.

Describe how thin layer chromatography (TLC) differs from traditional chromatography paper.
