A type of chromatography in which the stationary phase is an insoluble material packed into a glass or metal column
Chromatography that uses a solid support in a vertical column or tube.
chromatography that uses selective adsorption by a column of powders
a method for analysing or separating the components or dissolved substances of liquid mixtures. The sample is poured into the top of a column packed with an adsorbing material and washed through with a solvent. Different components adsorb to different extents and so move through the column at different rates. They are eluted in the liquid from the bottom of the column at different times as fractions. If the column material is more polar than the solvent, the components are separated by their differences in polarity, with the less polar components passing through the column faster than more polar ones.
Any form of chromatography that uses a column to hold the stationary phase. Open column chromatography, HPLC and open tubular capillary chromatography are all examples.
A technique used to separate the components of biologically active molecules, which move at different speeds through a hollow column that is filled with a chemically reactive material.
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.
Column chromatography in chemistry is the preparative application of chromatography. It is used to obtain pure chemical compounds from a mixture of compounds on a scale from micrograms up to kilograms using large industrial columns.
