Dionex™ SolEx™ HRPHS Polymer-Based SPE Cartridge

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.

About Dionex SolEx SPE Cartridges

Dionex SolEx SPE Cartridges extract organic pollutants from a liquid sample off-line using a solid-phase adsorbent. The cartridges employ a variety of chemistries depending on the application. The silica- or carbon-based absorbents are bound or encapsulated in a membrane filter (called disk format), or packed in a cartridge (syringe bodies). Water (ground, waste, and drinking) is the most common liquid sample extracted, but these SPE cartridges are also used to extract contaminants from milk, fruit juices, urine, and other matrices. These cartridges are desgined for use with Dionex AutoTrace 280 SPE system or other SPE instrumentation and vacuum manifolds.
