PAPER CHROMATOGRAPHY

Whatsapp Order

Paper Chromatography is an analytical laboratory technique used to separate and identify mixtures of substances based on their differential migration across a specially treated paper medium. It is widely used for qualitative analysis of compounds such as pigments, amino acids, and pharmaceuticals. The process involves applying a small sample spot onto chromatography paper and allowing a solvent to travel through the paper by capillary action, separating the components according to their solubility and affinity for the paper. This method is simple, cost-effective, and valuable in biochemical, pharmaceutical, and environmental laboratories for analyzing complex mixtures.
