[Allotrope] high-performance liquid chromatography system high-performance liquid chromatograph A high-performance liquid chromatograph is an instrument used for HPLC that is a technique in analytical chemistry used to separate the components in a mixture, to identify each component, and to quantify each component. It has pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out the column.
