- 1the chromotogrphyAnalysis method that allows the separation of gases or liquids from a mixture by selective adsorption, producing differently colored stains in the adsorbent medium; it is based on the different speed with which each fluid moves through a porous substance.

Chromatography of blood samples is often carried out in order to separate and identify substances contained in it, normally imperceptible, from the color they reflect on a support or subjected to a specific light. Such is the case of a specific drug or substance, such as alcohol. - 4Crime scene review. As in the movies: fabrics, fibers, tissues or other supports are taken to observe the adhesion separation of different substances, such as semen or blood, which at first glance could go unnoticed.Radioactivity detection.
Since radioactive elements have different emission rates and activities than ordinary matter, they can often be identified using this technique in the laboratory, exposing matter to substances that demonstrate a change in reaction rate. - 5Control of the industrial spirit of spirits. By means of gas phase chromatography, the quality basic components present in the liquor (ethanol, methanol, acetaldehyde, acetal, etc.) can be identified and quantified, thus allowing responsible administration of said compounds.
