Liquid Chromatography 
Liquid Chromatography is a is a separation technique in which the mobile phase is a liquid. This technique can be done on either a column or a plane. Nowadays liquid chromatography is done by high performance liquid chromatography.
In High Performance Liquid Chromatography, the sample is forced by the mobile phase, a liquid at high pressure, through a stationary phase column that is irregularly packed, has spherically shaped particles, or a porous monolithic layer.
