Product description Specification Document

PS-RP / PS-OH– / PS-H+ / PS-Mix / PS-Ag+ / PS-Ba2+

Polymer-based SPE phases for RP and ion chromatography

Features
- Base material: high purity polystyrene-divinylbenzene copolymers (PS/DVB),
- pore size 100 Å, particle size 100 µm
- very low degree of swelling, thus very well suited for chromatography
- reliable function over the whole pH range from 0–14
- different modifications for different applications from elimination of nonpolar compounds up to the removal of specific polar components

Recommended applications:
- Removal of interfering compounds
→ improves chromatographic separation, 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
- Enrichment of the analytes

Properties of the individual modifications;

PS-RP
- hydrophobic PS/DVB copolymer
- removal of interfering organic components from water

PS-OH–
- strong PS/DVB anion exchanger, OH– form
- capacity 0.6 meq/g
- removal or concentration of anions from water
- increasing the pH value in acidic samples

PS-H+
- strong PS/DVB cation exchanger, H+ form
- capacity 2.9 meq/g
- removal or concentration of cations from water
- decreasing the pH value of basic samples

PS-Mix
- mixture of PS-OH– and PS-H+
- desalting of water

PS-Ag+
- strong PS/DVB cation exchanger, Ag+ form
- removal of halide ions from water

PS-Ba2+
- strong PS/DVB cation exchanger, Ba2+ form
- removal of sulfate ions from water
