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). WebYou will usually start at a 2% solution (98 parts hexanes, 2 parts ethyl acetate) to get things moving slowly at first (hexanes is SUPER non-polar, so most compounds aren't highly soluble in it).
