Carbon beads, process of producing the same and chromatography column containing the same.

摘要

Carbon beads useful as a packing of liquid chromatography column are disclosed. The carbon beads according to the present invention has a pore volume index (10-50)/(1-50) of not less than 50%, total pore volume of not less than 0.15 ml/g, total volume of pores with radii of not less than 50 nm of not more than 0.1 ml/g, and a carbon content of not less than 97% by weight.
