Ceramospher
Ceramospher HPLC columns are manufactured by Osaka-Soda in Japan. Previously, the columns belonged to the Shiseido Company, whose chromatography division was acquired by Osaka Soda in 2017. Ceramospher is a special type of column for optical separation where the optically active metal complex Δ-Ru(phen)32+ is adsorbed to porous spherical ceramics by cation exchange.
There are two types of Ceramospher columns: RU-1 and RU-2. RU-2 packing material is created from RU-1 by further special hydrophobic treatment. Consequently, Ceramospher RU-2 allows the use of aqueous (reversed phase) mobile phases. These columns are very well suited for the optical separation of neutral or acidic compounds. They are characterized by a high loadability and durability.
