General description
Amphoteric properties of Dowex Retardion 11A8 allows specific isolation of elements from complex mixtures which generally is possible with use of monofunctional ion exchangers. Determination of trace amounts of Zinc and Cadmium by radiochemical NAA was performed using Retardion 11A8.
The Retardion 11A8 is not a true mixed bed resin, but a resin with mixed functionality. It contains paired anion and cation exchange sites (each exists as the other′s counter-ion) that adsorb mobile ions from a bulk stream.
Application
Dowex Retardion 11A8 was used in solid phase extraction for determination of total concentrations by flame atomic absorption spectrometry.
Chromatographic resin for ion separation. Useful for removal of ionic detergents (e.g., SDS) from protein samples. It is used for the removal of electrolytes from water solutions, and separation of cations from anions. Desalting occurs by SEC-type mechanism, so column use is recommended for best success.
Physical form
Mixed bed
Other Notes
This ion-exchange resin has not been specially processed nor cleaned. We suggest that it be treated to a suitable preliminary elution and wash.
