SFC Diol is another commonly used stationary phase in Supercritical Fluid Chromatography. It is composed of high-purity silica support that is chemically bonded with polar diol groups. This stationary phase provides unique selectivity based on hydrogen bonding interactions. Applications: SFC Diol is well-suited for the separation of polar and moderately polar compounds including carbohydrates, nucleosides, organic acids, and other hydrophilic compounds. It is particularly useful in analyzing complex mixtures and food samples, where retention of polar analytes is essential.
