Inertsil® CX

Inertsil® CX

Strong Cation Exchange Column


Inertsil CX has Benzenesulfonyl groups bonded to Silica gel by an alkyl chain. The Sulfony groups at the end of the structure offer cationic functions required for the cation exchange chromatography. It is mainly used for analyses of basic compounds. Inertsil CX has high ion exchange capacity and provides high retentivity and selectivity. Therefore, It is also suited for analysing amino acids and nucleobases.
