Column Chromatography

Science / Chemistry / Column Chromatography: Column chromatography is a method for separating mixtures. A solution containing the mixture is passed through a narrow tube packed with a stationary phase. Different substances in the mixture have different affinities for the stationary phase, and so move through the tube at different rates. This allows the substances in the mixture to be detected or collected separately as they reach the end of the tube.

High Performance Liquid Chromatography

Science / Chemistry / High Performance Liquid Chromatography: An efficient form of column chromatography that pumps a liquid solution of the sample at very high pressure through a column packed with a stationary phase made of very tiny particles. The high pressu MORE

Thin Layer Chromatography

Science / Chemistry / Thin Layer Chromatography: A technique for separating components in a mixture on the basis of their differing polarities. A spot of sample is placed on a flat sheet coated with silica and then carried along by a solvent that so MORE
