Florisil is widely used as an adsorbent in solid-phase extraction (SPE) and column chromatography for the separation and purification of various compounds. It is particularly effective in cleaning up complex mixtures in environmental, food, and pharmaceutical samples. Commonly applied in pesticide residue analysis, Florisil helps remove interfering substances such as pigments, fats, and hydrocarbons from extracts. It is also used in the processing of edible oils and in the analysis of vitamins and hormones due to its ability to selectively retain polar impurities while allowing target analytes to pass through. Its high surface area and consistent activity make it a reliable choice for reproducible sample preparation in analytical laboratories.
