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). WebIon exchange chromatography is the reversible adsorption of charged molecules to immobilized ion groups on a matrix of an opposite charge. Separation can be selectively achieved by adsorption and release of samples from the matrix. Ion exchange starts with the equilibration of the exchanger using pH, and ionic strength.
