Chromatography has numerous applications in biological and chemical fields. It is widely used in biochemical research for the separation and identification of chemical compounds of biological origin. …

Paper chromatography has become standard practice for the separation of complex mixtures of amino acids, peptides, carbohydrates, steroids, purines, and a long list of simple organic compounds.

Examples are (1) water held by cellulose, paper, or silica, or (2) a thin film coated or bonded to a solid. The solid support ideally is inactive in the retention of solutes, but it actually is not; retention is mostly …

Nov 12, 2025 · In the petroleum industry the technique is employed to analyze complex mixtures of hydrocarbons. As a separation method, chromatography has a number of advantages over older …

The various chromatographic methods are characterized in terms of the mobile phase—gas: gas chromatography (GC); liquid: liquid chromatography (LC); supercritical fluid: supercritical-fluid …

In paper chromatography a sheet or a narrow strip of paper serves as the stationary phase. In thin-layer chromatography a thin film of a stationary phase of solid particles bound together for mechanical …

Chromatography usually is divided into two categories depending on the type of mobile phase that is used. If the mobile phase is a liquid, the technique is liquid chromatography; if it is a gas,…

Partition chromatography utilizes a support material coated with a stationary-phase liquid. Examples are (1) water held by cellulose, paper, or silica, or (2) a thin film coated or bonded to a solid.

Oct 8, 2025 · Normal-phase chromatography involves a polar stationary phase and a less polar mobile phase. Liquid-liquid chromatography employs liquid mobile and stationary phases.
