Cleanert HXN is also made of polydivinylbenzene having surface modified with vinylpyrrolidone. This sorbent is specially designed to extract sulfonyl ureas from water and soil at ppb level. It is less polar than Cleanert PEP and can also be used to extract, enrich and clean up samples from mid polar to high polar compounds.
Based on polystyrene/divinylbenzene;
Average Particle Diameter: 40-60 μm;
Average Pore Size: 70 Å;
Specific Surface Area: 600 m2/g
