LC-Si silica

Non-polar compounds elute first on a normal phase silica column, while more polar solutes exhibit stronger interaction with the silanol groups on the silica surface. Typical mobile phases consist of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small amount of polar solvent. Silica is frequently used in preparative chromatography due to its low operating cost compared to reversed-phase columns. Suitable for L3 per USP.
The polar selectivity of silica is helpful for the separation of mycotoxins, also to resolve positional isomers.
