WebLC-MS/MS separates chemical compounds using traditional liquid chromatography, the analytes are then directed into a series of quadrupoles where they are ionized as the molecular ion then fragmented and selected fragments are detected and quantified. The determination of both molecular ion and fragment ions permits more accurate … WebThe flow rates used in LC-MS should be less than those used for HPLC. This is to ensure complete ionization and to maintain the detection sensitivity of the MS, which starts to decrease beyond 200 µL/min. Therefore, the column in LC-MS is much smaller to accommodate the smaller solvent flow rates and sample volumes. lithia motors linkedin
