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.[1] DE is an effective alternative to chemical pesticides.[2] DE, amorphous silica which is crushed and calcined to form cristobalite.[3]
Reagent-grade Celite® 545 AW. Acid-washed, high-purity fluxcalcined diatomaceous silica, especially prepared for chromatography and other laboratory applications.

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
