High-Performance Liquid Chromatography

Definition

High-Performance Liquid Chromatography (HPLC) is a powerful analytical technique used to separate, identify, and quantify components in a mixture. It uses high pressure to push a liquid solvent through a column packed with stationary phase material, allowing for precise separation of compounds based on their interactions with the stationary phase. This technique is crucial in fields such as pharmaceuticals, environmental testing, and, importantly, in analyzing biomaterials for tissue engineering applications.
