| General description: | A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent. Non-polar compounds will elute from the column first, while polar solutes show stronger interaction with the silanol groups on the silica surface. The polar selectivity of silica is very helpful for separating mycotoxins. Silica is frequently used in preparative chromatography due to its low operating cost and back pressure compared to reversed-phase columns. Silica is particularly popular among organic chemists as a low-pressure preparative tool. The unmodified silica in SUPELCOSIL LC-Si columns also separate positional isomers. |
