HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC)

High Performance Liquid Chromatography (HPLC) An analytical separation technique that involves the high-pressure flow of a liquid through a column that contains the stationary phase. Stationary phase: Can be a solid (LSC) or a liquid (LLC) A mixture of compounds injected at one end of the column separates as the compounds pass through.
