Finex chromatographic resins are mainly strong acid cation exchange resins, made by sulphonation of homogenous beads of styrene-divinylbenzene copolymer. The process parameters are very carefully controlled both in the polymerization and the sulphonation stages in order to yield the high and reproducible standards of Finex resins.

Finex chromatographic resins are either gel type, meso- or macroporous, the physical and chemical properties of which are tailored specifically for optimal service in production. We have developed a flexible and adaptive production process so that we can tailor the resin’s properties to suit each customer’s needs.

We can readily adjust the bead size distribution, cross-linkage and ionic form to suit any particular application. Please do not hesitate to contact us and let us know your special needs.
