SCX sorbent has benzenesulfonic acid as a bonded functional group with a very low pKa. The presence of the benzene ring in the functional group increases its potential for non-polar interaction. The two properties are quite useful in the absorption of cationic organic compounds from aqueous systems where non-polar compounds are seen.

This HLB sorbent will provide reversed-phase cleanup of acidic,basic and neutral compounds form complex sample matrices.HLB hasbeen designed to simplify SPE with easy to follow protocols.It also pro-duces cleaner samples by removing greater than 95%of common matrixinterferences such as salt,proteins and phospholipids

C18 solid phase extraction column
Reversed phase C18 extraction column with silica gel as matrix. It has the characteristics of high bonding density, low loss and high recovery.
