LLG CHROMATOGRAPHY CATALOGUEChromatographySample preparation/SPE1SPE phases for RP/ ion chromatographySPE phases for polymer-based RP and ion chromatographyMACHEREY-NAGEL1Base 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.Reliable function over the whole pH range from 0-14. Different modifications for different applications from eliminationof 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 columnpackingEnrichment of the analytesremoval of organic interfering components from waterremoval or concentration of anions from water increasingthe pH value in acidic samples removal or concentration ofcations from waterdecreasing the pH value in basic samplesremoval of halide ions from waterremoval of sulphate ions from waterPS-RP hydrophobic PS/DVB-copolymerPS-OH - strong PS/DVB anion exanger, OH - form capacity0.6 meq/gPS-H + strong PS/DVB cation exchanger, H + form, capacity2.9 meg/gPS-Ag + strong PS/DVB cation exchanger, Ag + formPS-Ba² + strong PS/DVB cation exchanger, Ba² + FormPhase Capacity Capacity PK Cat.
