TLC layers can be prepared in the lab, but they are normally purchased as pre-coated plates. There is a diverse range of options available – from silica, aluminum oxide or cellulose, to modified or mixed-layer plates.

WebSep 25, 2024 · Normal phase. Normal phase HPLC systems are similar to the flash-column chromatography that you might be familiar with. A silica stationary phase is eluted with a non-polar solvent such as hexane, or a fairly non-polar solvent mixture such as 2-propanol in hexanes. In normal phase chromatography, only organic solvents are used. WebIt is based on the compound’s solubility with the solvent and the difference in the affinity for the mobile phase versus the stationary adsorbent (silica). In normal phase chromatography, where non-polar solvents such as hexane or pentane are used, non-polar compounds will move up the plate while most polar compounds will stay on the baseline.
