Chromatography is a separation technique mostly employed in chemical analysis. Nevertheless it is also used for preparative purposes, particularly for the isolation of relatively small amounts of materials that have comparatively high value. Chromatography is probably the most powerful and versatile technique. In a single step process it can separate a mixture into its individual components and simultaneously provide an quantitative estimate of each constituent.

The first scientist who recognize chromatography as an efficient method of separation was the Russian botanist Tswett , who used a simple form of liquid-solid chromatography to separate a number of plant pigments. The colored bands he produced on the adsorbent bed evoked the term chromatography for this type of separation.
