Naturally occurring amorphous silicic acids of fossil origin, also known as diatomaceous earth or diatomite. Purified for chromatographic applications. Compared to silica, kieselguhr has a small surface of low activity (application in partition chromatography). After impregnation with various substances (paraffin, silicone oil, undecane) it can be used for reversed phase chromatography.
