Description

Chromatography paper is a high-purity cellulose material specifically designed for separating the individual components of a mixture based on their varying rates of migration. In a typical laboratory setup, a solvent moves across the paper through capillary action, carrying different solutes along at different speeds depending on their solubility and molecular size. This process creates a visual “map” or chromatogram, making it an essential tool for identifying substances such as ink dyes, plant pigments, or amino acids in both educational and analytical chemistry.
