Chromatography
Chromatography is an analytical technique commonly used for separating a mixture of chemical substances into its individual components, so that the individual components can be thoroughly analyzed. There are many types of chromatography e.g., liquid chromatography, gas chromatography, ion-exchange chromatography, affinity chromatography, but all of these employ the same basic principles.Chromatography may be either preparative or analytical technique. The main purpose of preparative chromatography is to separate the components of a mixture for later use which is a form of purification. Analytical chromatography is done normally with small amounts of samples which is majorly for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually limited. Several types of chromatographic techniques are involved in the chromatography in which each type of chromatographic method deals with each type of particular separation techniques.
