Expertise in Sample Preparation

Ion Exchange Resins for Analytical Applications
Eichrom supplies an expanding range of cation and anion exchange resins, purified for the needsof analytical applications. These resins are comparable in quality and performance to the AG®
Resins supplied by Bio-Rad® Laboratories. Eichrom Technologies has 16 years of expertise inanalytical sample preparation and possesses technical support facilities for radiological and wet
chemical applications. Our focus is the development and support of sample preparation
methodologies for chemical and biochemical analysis.
Cation Exchange Resins
Eichrom’s line of cation exchange resins for analytical applications are type 50W strong acidcation exchange resins (sulfonic acid exchange groups on styrene divinyl benzene polymericbeads.) Our resins are available in 4% and 8% DVB cross linkages. All our cation exchange
resins are provided in hydrogen form.
