Sidebar: It's Okay To Be FastHigh-performance liquid chromatography (HPLC) is a mainstay of biological and chemical research, analytical, and production laboratories. After a researcher loads a sample mixture, the instrument pumps mixtures of solvents-usually at high pressures-through a column packed with a material that slows individual compounds to different degrees, separating the substances as they pass through the column. Once the journey is complete, a detector and often an automatic fraction collector are charged with redirecting the solvent stream into separate, purified fractions.
BRAINY: Isco's Foxy 200 collects HPLC fractions by time, volume, or peak.
