Description générale

Celpure® P300 (Diatomaceous earth, DE) is natural amorphous silica formed from the fossilized skeletons of diatoms. It is extracted, crushed, dried and calcined with or without flux material. DE is widely used as filler in construction materials, paints and as an anti-caking agent for agricultural chemicals. It has high water and oil absorption ability. The potential toxicity of different samples of DE has been assessed. DE is also employed as an adsorbent for column chromatography.

Application

Celpure® P300 has been used used in the column chromatographic isolation and extraction of testosterone and corticosterone from freeze-dried water dragon plasma samples.
For high-purity, high-throughput processes
