CHROMABOND PS phases

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 For applications click here.

Properties of the individual modifications
PS-RP	hydrophobic PS/DVB copolymer	removal of interfering organic components from water for standard protocol see application 304033
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 for standard protocol see application 304035
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 for standard protocol see application 304036
PS-Mix	mixture of PS-OH^– and PS-H⁺	desalting of water for standard protocol see application 304037
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
