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. Florisil is effective in promoting [1,3]-sigmatropic shift of myceophenolic acid related allyl phenyl ethers. Florisil cartridges are used in atmospheric sampling to assess possible interference from air contaminants.

Application

Florisil was used:

• as column packing material in column chromatography
• as an adsorbent in gas chromatography with electron capture detector (GC/ECD), capillary column chromatography, adsorption column chromatography
• in clean-up procedures in gas chromatography-tandem mass spectrometry and GC-FID
