| CHROMABOND® HR-X Spherical, hydrophobic polystyrene- divinylbenzene resin for SPE. Hydrophobic polystyrene-divinylbenzene copolymer. pH stability 1–14. High-purity material with highest reproducibility and lowest blank values due to a novel manufacturing process. Spherical particles 85 Ìm; pore size 55 – 60Å. Very high surface 1000m2/ g. Capacity 90mg/g (caffeine in water). Excellent recovery rates especially for the enrichment of pharmaceuticalsactive ingredients due to the spherical structure of the particles, very homogeneous surface, and optimised pore structure. |
