Use of sulfonated hypercross-linked polystyrene in ion chromatography

The development of hyper-cross-linked polystyrene (HCPS) opens new possibilities in ion-chromatographic analysis. HCPS and HCPS-based sorbents have some advantages over the analogues based on styrene and divinylbenzene. The high degree of cross-linking in HCPS provides a higher mechanical strength, thermal and hydrolytic stability, and insignificant swelling in organic solvents.
