Title: hydrophobic-interaction chromatography Long Title: IUPAC Gold Book - hydrophobic-interaction chromatography DOI: 10.1351/goldbook.09891 Status: current Definition Chromatography in which molecules are separated by interactions between their hydrophobic moieties and hydrophobic sites on the surface of the stationary phase. Note High salt concentrations are used in the mobile phase and separations are effected by changing the salt concentration. Gradients are run by decreasing the salt concentration over time.
