Dowex Marathon MR-3 is a premium, premixed, mixed bed product designed for polishing demineralized water to conductivities <0.1 μS/cm. Marathon MR-3 is a 1:1 equivalent mixture of Marathon C-10 (H) and Marathon A (OH)
Dowex® Marathon™ MR-3 hydrogen and hydroxide form was used in assessing inorganic nitrogen in litter layer and soil using ion-exchange resin bags on Alpkem autoanalyzer and by ion chromatography.
Mixed bed ion exchange resin specially processed resin for condensate polishing; best for in-process and column demineralization.
1 kg in poly bottle
100, 500 g in poly bottle
Uniform size beads offer higher surface area for increased capacity and faster kinetics. Nuclear grade, gel form, styrene-divinylbenzene copolymer matrix
The Dowex® Marathon™ MR-3 is a superior resin to the Dowex MR-3. The Dowex Marathon series provides narrower particle Distribution, better efficiency, and improved kinetics when compared to the gaussian Dowex products.
This ion-exchange resin has not been specially processed nor cleaned. We suggest that it be treated to a suitable preliminary elution and wash.
