Descrizione generale

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.

Applicazioni

  • Celite® 545 AW was used as stationary phase in purification of fagopyritols using preparative chromatography.[4]
  • Celite® 545 AW was used as packing material for fractionating procedure and the fractions were analysed using GC-ECD, GC/ECNI-MS[5] and IC-MS/MS.[6]
