May 28, 2022 · HPLC, aka High-Performance Liquid Chromatography, is a separation technique in analytical chemistry used to identify, quantify and separate molecular compounds in a liquid mixture. Liquid chromatography (LC) is a very well-established technique. HPLC is the most widely used LC technique in the pharmaceutical industry to identify and quantify
-
High-performance liquid chromatography (HPLC) is a broad analytical chemistry technique used to separate compounds in a chemical mixture. These separations utilize the pressure-driven flow of a mobile phase through a column packed with a stationary phase. The mobile phase carries a liquid sample through the column to the detector, and compounds
