Waters Corp Sep-Pak Porapak RDX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 125-150 µm, 30/pk
Specially cleaned polymeric poly(divinylbenzene-vinylpyrrolidone) resin with hydrophobic character. Can be used as an alternative to octadecyl-bonded silica for preparation of analytes that weakly adsorb to silica-based reversed-phase sorbents. Compatible with sample or eluents at high and low pH. Specifically designed for the concentration of high explosives in aqueous samples.
