LC-MS definition

LC-MS means liquid chromatography-mass spectrometry, an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry
LC-MS means liquid chromatography/mass spectrometry, which is a technique used to provide information about the molecular weight, structure, identity, and quantity of specific sample components.
