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
