chromatography definition chemistry

Kids.Net.Au - Encyclopedia > Chromatography

In chemistry, chromatography is a process for separating different components from a mixture. This is achieved by passing a sample mixture (the "analyte") in a stream of solvent (the "mobile phase") through some form of material (the "stationary phase") that will provide resistance by virtue of chemical interactions (not reactions) between the components of the sample and the material.

Filtration Definition and Processes (Chemistry) - ThoughtCo

Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. The term "filtration" applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate.

Thin-layer chromatography - Wikipedia

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography is performed on a sheet of glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide (alumina), or cellulose.This layer of adsorbent is known as the stationary phase.
