High Performance Liquid Chromatography (HPLC) is a process of separating components in a liquid mixture. A liquid sample is injected into a stream of solvent ( mobile phase ) flowing through a column packed with a separation medium ( stationary phase ).

High performance liquid chromatography (HPLC) is a very useful analytical technique with various applications. HPLC involves the adsorbent material column (such as silica beads) where the sample is forwarded under pressure. Each sample mixture component will interact differently from the material in the column, and thus, has a different flow rate.
