Florisil Column Plates for Solid Phase Extraction

B&M® Florisil is an adsorbent of Florisil-MgO-SiO2 bound to silica gel magnesium oxide, which consists of three main components: silicon dioxide (84%), magnesium oxide (15.5%) and sodium sulfate (0.5%).
Similar to silica gel, this adsorbent is highly polar, highly reactive and weakly basic for the extraction of polar compounds from non-polar solutions and is used for the adsorption of weakly and moderately polar compounds from non-aqueous solutions. The large particle size in the Florisil package allows for faster processing of large sample volumes and can therefore be used in place of silica gel mini-columns when the samples have high viscosity.

In addition, Florisil can be used in place of alumina products in alumina columns when Lewis acid, which is part of the alumina, interferes with extraction.
