What Is Chromatography Used For

What Is Chromatography Used ForIn paper chromatography, the stationary phase is a really uniform absorbent paper. The mobile phase is actually a suitable liquid solvent or mixture of solvents

You probably employed paper chromatography as among the first things you ever did in chemistry to separate out mixtures of coloured dyes, for instance, the dyes which constitute a particular ink. That is an easy instance to take.

Types of Chromatography

Chromatography is a nondestructive process for solving a complex combination into its individual compounds or fractions. This is a separation process and the separated entities are recognized by other analytical methods like Infrared, UV-visible, Mass spectroscopy, NMR (nuclear magnetic resonance) and so on. For quantitative analysis the dimension of the area under the curve within chromatogram is done.

You can find four principal types of chromatography. The different types are: Gas chromatography, liquid chromatography, paper chromatography and thin-layer chromatography.

High Pressure Liquid Chromatography

High performance liquid chromatography (formerly known as high-pressure liquid chromatography), HPLC, is an approach in analytic chemistry employed to separate the elements in a mixture, to recognize each element and to quantify every component.

Chromatography can be explained as a mass transfer procedure involving adsorption. HPLC depends on pumps to move a pressurized liquid plus a sample mixture via a column loaded with a sorbent, resulting in the separation of the sample elements.


The sample mixture being analyzed and separated is introduced, in a discrete tiny volume (typically micro-liters), to the stream of mobile phase percolating via the column. The elements of the sample pass through the column at various velocities, which are function of certain physical interactions with the sorbent (also referred to as stationary phase).
