Remove high levels of alkaline earth and transition metals, neutralize basic samples, and filter particulates with the Thermo Scientific™ Dionex™ Guardcap™ H vial caps. Designed for use with Thermo Scientific™ Dionex™ AS-DV Autosampler PolyVials, Dionex Guardcap H vial caps contain sulfonated strong cation exchange resin in the hydronium form that is embedded in a high density polyethylene matrix. Dionex Guardcap H vial caps seamlessly integrate automated inline sample preparation into your existing sample workflow without the need for additional labor, time, and complexity.

Each Guardcap H vial cap:
  • Removes 1000mg/L divalent cation (e.g., calcium or transition metals) from 800μL of sample
  • Neutralizes up to 500μL of 50mM NaOH or other base
  • Filters more than 80% of particulate matter greater than 20μm in diameter
Obtain Superior Analytical Results with Greatly Reduced Effort

Increase the lifetime of your analytical columns and suppressors by removing metals, matrix ions and particulates that can result in fouling.

Convenient and Easy to Use

Dionex Guardcap H vial caps come in the familiar filter cap format used with Dionex PolyVials. If you can load a filter cap on a Dionex PolyVial, you can use Dionex Guardcap H for automated inline sample preparation. Unlike Dionex OnGuard™ II H cartridges, Dionex Guardcap H vial caps require no pretreatment procedures prior to use.
