Description

General description

Florisil, adsorbent for the separation of lipids, is a commercially-prepared magnesia silica gel. It has a coarse mesh size which helps in rapid flow rate.[1] Florisil is effective in promoting [1,3]-sigmatropic shift of myceophenolic acid related allyl phenyl ethers.[2] Florisil cartridges are used in atmospheric sampling to assess possible interference from air contaminants.[3]

Application

Florisil was used:

• as column packing material in column chromatography[4]
• as an adsorbent in gas chromatography with electron capture detector (GC/ECD)[5], capillary column chromatography[6], adsorption column chromatography.[7]
• in clean-up procedures in gas chromatography-tandem mass spectrometry[7] and GC-FID[8]
