SPE phases for polymer-based RP and ion chromatography

Base material: high-purity polystyrene-divinylbenzene copolymers (PS/DVB)
pore size 100 Å, paricle size 100µm. Verly low degree of swelling, thus very well suited for chromatography. Different modifications for different applications from elimination of nonpolar compounds up to removal of specific polar comonents.

Recommended application:
Removal of interfering compounds

  • improves chromatographic separtions, if the interfering components overlap with the analyte in the chromatogram
  • improves lifetime of the chromatographic column, since interfering components can irreversibly block the column packing
  • removal or concentration of anions from water increasing the pH value in acidic samples removal or concentration of cations from water PS-OH strong PS/DVB anion exanger, OH form capacity 0,6 meq/g
  • decreasing the pH value in basic samples PS-H+ strong PS/DVB cation exchanger, H+ form, capacity 2,9 meg/g
