| Résumé≠ | Thin-Layer Chromatography (TLC) is a planar chromatographic technique that separates compounds based on their differential affinities for a mobile and stationary phase. Developed by Egon Stahl in 1956, TLC remains one of the most accessible and widely used analytical methods in organic and inorganic chemistry, laboratories, and quality control. | Column chromatography is a liquid separation technique in which a stationary phase (typically silica gel or alumina) is packed into a vertical column, and a mobile phase (solvent) percolates through it to separate mixture components. Pioneered by Mikhail Tsvet in 1903, column chromatography remains the workhorse of organic chemistry laboratories for purifying reaction products and isolating target compounds. |
