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.[1]

Application

Florisil was used:

as column packing material in column chromatography[2]
as an adsorbent in gas chromatography with electron capture detector (GC/ECD), capillary column chromatography, adsorption column chromatography[3]
in clean-up procedures in gas chromatography-tandem mass spectrometry[3] and GC-FID[4]

Legal Information

Florisil is a registered trademark of U.S. Silica Company

An improved gas chromatographic method for the determination of perfluorocarbon tracers in the atmosphere

Lagomarsino, Raymond J.

Journal of Chromatographic Science, 34, 405-412 (1996)

Impact of the plant rhizosphere and augmentation on remediation of polychlorinated biphenyl contaminated soil.

Andrew C Singer et al.

Environmental toxicology and chemistry, 22(9), 1998-2004 (2003-09-10)

This study investigated the interactive effects of bioaugmentation, biostimulation, and the rhizosphere during remediation of Aroclor 1242-contaminated soil. Treatments were repeatedly augmented with polychlorinated bipheny (PCB)-degrading bacteria, inducers (carvone and salicylic acid), surfactant (sorbitan trioleate), minimal salts medium in a

Determination of atmospheric perfluorocarbon background concentrations of fL/L range at the western coastal area of Korea

Atmospheric Environment, 1, 4-4 (2002)

Rapid analytical method for the determination of pesticide residues in sunflower seeds based on focused microwave-assisted Soxhlet extraction prior to gas chromatography-tandem mass spectrometry.

R C Prados-Rosales et al.

Journal of chromatography. A, 993(1-2), 121-129 (2003-05-09)

A rapid analytical method for determination of organochlorine pesticide residues in sunflower seeds based on focused microwave-assisted Soxhlet extraction has been developed. The main factors affecting the extraction efficiency--namely microwave power, irradiation time, volume of extractant and number of cycles--were

Determination of methanol and ethanol by gas chromatrography following air sampling onto florisil cartridges and their concentrations at urban sites in the three largest cities in Brazil.

P A de Paula Pereira et al.

Talanta, 49(2), 245-252 (2008-10-31)

A new sampling protocol was developed to determine methanol and ethanol in the gas phase, at low concentration levels, in urban atmospheres. The procedure involves collection of air samples (20.0-30.0 l) with three florisil cartridges connected in series, at a

How can I determine the shelf life / expiration / retest date of this product?

  If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
  For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
  For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?

1 answer
1. Technical Support

  Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
