General description

Diatomaceous earth [Celite 545 AW] is considered as skeletal remains of single-celled algae/diatoms formed due to sedimentary deposits. DE is a surface-active agent which causes abrasion and adsorption of the cuticular lipids. DE is an effective alternative to chemical pesticides. DE, amorphous silica which is crushed and calcined to form cristobalite.
Reagent-grade Celite® 545 AW. Acid-washed, high-purity fluxcalcined diatomaceous silica, especially prepared for chromatography and other laboratory applications.

Application

  • Celite® 545 AW was used as stationary phase in purification of fagopyritols using preparative chromatography.
  • Celite® 545 AW was used as packing material for fractionating procedure and the fractions were analysed using GC-ECD, GC/ECNI-MS and IC-MS/MS.

The molecular structure of fagopyritol A1, a novel galactopyranosyl cyclitol from buckwheat seeds, was determined to be O-alpha-D-galactopyranosyl-(1 --> 3)-D-chiro-inositol by 1H and 13C NMR. Fagopyritol A1 is a positional isomer of fagopyritol B1 (O-alpha-D-galactopyranosyl-(1 --> 2)-D-chiro-inositol), representing a different

The separation properties of different chromatographic methods regarding the enantioselective separation of axially chiral (atropisomeric) polybrominated biphenyls (PBB) were studied. For this purpose, the technical hexabromobiphenyl product Firemaster BP-6 was characterised by gas-chromatography coupled to electron capture detection (GC/ECD) and
