CHROMABOND® HR-X | Volume ml: 3, Capacity mg: 200
Merk: Macherey-Nagel GmbH & Co. KGBeschikbaar in 13 variantenSpherical, hydrophobic polystyrene-divinylbenzene resin for SPEHydrophobic polystyrene-divinylbenzene copolymer pH stability 1 to14. High-purity material with highest reproducibility and lowest blank values due to a novel manufacturing process, spherical particles 85mm; pore size 55 to 60Å. Very high surface 1000m²/g; capacity 390mg/g (caffeine in water). Excellent recovery rates especially for the enrichment of pharmaceuticals/active ingredients due to the spherical structure of the particles, very homogeneous surface, and optimised pore structure.Recommended applications: pharmaceuticals/active ingredients from tablets, creams and water/waste water, drugs and pharmaceuticals from urine, blood, serum and plasma trace analysis of pesticides.

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 packing
