WebReversed-phase chromatography is a technique using hydrophobic molecules covalently bonded to the stationary phase particles in order to create a hydrophobic stationary phase, which has a stronger affinity for hydrophobic or less polar compounds. WebHydrophilic interaction liquid chromatography (HILIC) is a popular technique for the separation of polar compounds, which are poorly retained by reversed-phase liquid chromatography. ... Many HILIC bonded phases are silica-based, which are prepared by derivatization of the silica gel surface with polar groups.
WebBuilt on the renowned Hypersil silica backbone, the base-deactivated silica is one of the most popular packing materials available. For more challenging separations that require improved chromatographic performance, use Thermo Scientific™ Hypersil GOLD™ columns as an alternative.
