CHROMABOND® PS-OH- / PS-H+ | Phase: PS-H+, Volume ml: 3, Capacity mg: 200
Merk: Macherey-Nagel GmbH & Co. KGBeschikbaar in 4 variantenSPE phases for polymer-based RP and ion chromatographyBase 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. Different modifications for different applications from elimination of 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 chromatogramimproves lifetime of the chromatographic column, since interfering components can irreversibly block the column packingCHROMABOND® PS-OH- / PS-H+ | Phase: PS-H+, Volume ml: 3, Capacity mg: 200
