Normal-Phase Chromatography - an overview
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. The use of a hydrophobic stationary phase is essentially the reverse of normal phase … WebNormal-phase LC analysis is an effective method of separating phospholipid classes. Columns containing silica (3–10 μm diameter) as the stationary phase are used in … Webthe HPLC mobile phases, columns, and experiments must be reconfigured prior to analysis. Often a single sample set must be run in reverse phase, normal phase, MS+, and MS- modes in order to ensure detection of all potential metabolites. This requires two seperate LC methods, and two MS polarity methods, up to four analyses for the same sample. people lied and said they love me song
