LC, packing material (sorbents, bulk), diatomaceous earth, CELITE 535

Description

Naturally occurring amorphous silica of fossil origin, also known as diatomaceous earth, bacillary earth or diatomite. Specially cleaned for chromatographic applications. Compared to diatomite gel, diatomaceous earth has a small, less active surface area (used in partition chromatography). After impregnation with various substances (kerosene, silicone oil, undecane), it can be used for reversed phase chromatography.
