PAPER CHROMATOGRAPHY,

Author:GIREESH C M Date: March 5, 2026  Title Paper Chromatography: A Simple Method to Separate Substances Abstract Paper chromatography is a simple and effective technique used in chemistry to separate different components of a mixture. It is widely used in laboratories and educational settings because it is easy to perform and understand. This article explains the basic principle of paper chromatography, including the role of stationary and mobile phases. The study also highlights how substances move at different speeds depending on their interaction with the solvent and paper. The article aims to provide a clear understanding of the concept for students, especially those studying science and teacher education. Introduction Paper chromatography is one of the simplest techniques used in chemical analysis to separate mixtures. It is commonly used to identify different pigments, dyes, or components present in substances such as ink or plant extracts. The method works based on the mo...

A study on pigment separation using chromatography

 Title A Study on Pigment Separation Using Chromatography This study explores the separation of plant pigments through paper chromatography. The experiment focuses on identifying various pigments present in green leaves and understanding how chromatography helps separate mixtures based on differences in solubility and polarity. It demonstrates the practical application of chromatographic techniques in biology and chemistry laboratories for analyzing natural compounds. Abstract This study investigates the separation of plant pigments using paper chromatography. Leaf extracts were prepared using a suitable solvent and applied to chromatography paper. When placed in a solvent system, pigments separated into distinct bands due to differences in solubility and adsorption. The experiment successfully identified chlorophyll a, chlorophyll b, xanthophyll, and carotene. The findings confirm chromatography as an effective technique for separating and analyzing components of complex mixtures....
