Glossary Ultra Performance Liquid Chromatography

advanced technique for rapid chemical compound separation

Ultra Performance Liquid Chromatography (UPLC) is an advanced form of liquid chromatography that allows for faster and more efficient separation of chemical compounds in a mixture. It uses smaller particles and higher pressures than traditional High-Performance Liquid Chromatography (HPLC), resulting in better resolution, sensitivity, and speed, which is particularly useful in fields like pharmaceuticals, environmental testing, and biological research.
