WebLiquid chromatography-mass spectrometry (LC-MS) is the combination of two selective techniques that allows the analyte(s) of interest in highly complex mixtures to be isolated and measured. LC differentiates compounds by their physico-chemical properties and MS differentiates compounds by mass (specifically their mass-to-charge ratio).
