DESCRIPTION
Obtain high recovery of polyphenols and related substances, including humic acids and azo-containing substances such as azo dyes, by using the Thermo Scientific™ Dionex™ SolEx™ HRPHS Polymer-Based SPE Cartridge. The HRPHS stationary phase is a neutral resin comprised of a high-surface-area, divinylbenzene-based particle grafted with a polyvinylpyrrolidone polymer. This material has properties of a hydrophilic, reversed-phase substance and also has specific high capacity for polyphenols. The cartridge is dessigned for use with the Thermo Scientific™ Dionex™ AutoTrace™ 280 SPE system or other SPE instrumentation and vacuum manifolds.
