GlossaryUltra Performance Liquid Chromatography

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.
