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 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 sulphate ions from water
