Glossary High-Performance Liquid Chromatography

technique separating mixture components using high-pressure liquid flow

High-Performance Liquid Chromatography (HPLC) is a technique used in analytical chemistry to separate, identify, and quantify components in a mixture. It involves passing a liquid sample through a column filled with a solid adsorbent material under high pressure, allowing different substances to be detected based on their interaction with the adsorbent. This method is widely used in pharmaceuticals, environmental testing, and food safety to ensure the purity and concentration of various compounds.
