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 such as food extracts, environmental samples, and pharmaceuticals. Commonly applied in pesticide residue analysis, Florisil helps remove interfering substances like pigments, fats, and sterols, allowing for more accurate detection of target analytes. It is also used in the processing of oils and fats to separate different lipid classes. Due to its consistent performance and selectivity, Florisil remains a preferred choice in analytical laboratories for sample preparation prior to GC or HPLC analysis.
