Paper & Thin Layer Chromatography

This video tutorial covers paper and thin layer chromatography, focusing on their use in forensic science. Chromatography is a technique for separating components of a mixture, demonstrated using food coloring. The video explains the concept of stationary and mobile phases, and how solubility affects the distance traveled by components on chromatography paper. The retention factor (Rf value) is introduced as a measure of solubility. Thin layer chromatography (TLC) is also discussed, using a glass plate with a thin layer of absorbent material. The video concludes with applications of chromatography in identifying substances like drugs and inks.
