mass spectrometry ultra-performance liquid chromatography ultra-performance liquid chromatography-mass spectrometry 2020-06-16T17:39:24Z An analytical technique that combines the physical separation capabilities of ultra-pressure liquid chromatography (UPLC) with the mass analysis capabilities of mass spectrometry (MS). Molecular mixtures are initially separated into components by UPLC. As these components exit the column, they are subjected to mass spectrometry for identification based on their mass-to-charge ratio and behavior in a magnetic field.
