GlossaryUltra-Performance Liquid Chromatography Tandem Mass Spectrometry

advanced technique for separating and identifying compounds in samples

Ultra-Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS) is an advanced analytical technique used to separate, identify, and quantify compounds in a sample. UPLC enhances the resolution and speed of liquid chromatography, while MS/MS provides highly sensitive and specific detection by breaking down molecules into fragments and analyzing their mass. This method is widely used in fields like pharmacology, biochemistry, and environmental science for precise and accurate analysis of complex mixtures.
