Ion Exchange Columns

Inertsil CX Analytical Columns

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 is manufactured under strict quality　control in order to offer excellent batch to batch reproducibility as the same as Inertsil AX. Inertsil CX has high ion exchange capacity and provides　high retentivity and selectivity. Therefore, it is also suited for analyzing amino acids and nucleobases.
