Deionizing Analytical Grade Resin

Print

AG 501-X8
Mixed bed resins are used for deionizing water or other non-ionic substances such as urea, acrylamide, formamide, or glyoxal. Deionization is the complete removal of all ionic species from a solutionAG 501-X8 mixed bed resin for deionization consists of equivalent amounts of AG 50W-X8 strong cationexchange resin H+ form and AG 1-X8 strong anion exchange resin OH- form. Molecular BiologyGrade AG 501-X8 resin is certified to be endo- and exonuclease-free and to contain no ligase inhibitors. Biotechnology Grade AG 501-X8 resin is certified to contain less than 100 micro-organisms per gram. AG 501- X8(D) resin and and Bio-Rex MSZ 501(D) resin have a blue dye irreversibly bound to the anion exchange resin, which turns from blue to gold when the exchange capacity is exhausted.

Applications: AG 501-X8 and Bio-Rex MSZ 501(D) mixed bed resins may be used to prepare non-ionic reagents for critical analytical applications. Either the batch or column method may be used to obtain purified urea, acrylamide, formamide, glyoxal, or PEG, although the batch technique is much more common.

AG 11 A8
AG 11 A8 ion retardation resin is extremely useful for chromatographic desalting, or removing acid from non-ionic molecules. It separates salts from organic materials by absorbing both anions and cations in equivalent amounts while allowing the organic compounds to pass through. Both analytical and biotechnology grades of AG 11 A8 resin are available. Biotechnology grade 11 A8 resin is certified to contain less than 100 microorganisms per gram of resin.

The AG 11 A8 resin selectively retards ionic substances, so it can be used for desalting non-ionic solutions and for separating ions from ionic substances. Organic molecules, even ionic species such as acidic and basic amino acids, are usually not absorbed by AG 11 A8 resin, whereas inorganic ions are absorbed, thus achieving the separation.

AG 11 A8 resin is made by polymerization of acrylic acid moieties inside the AG 1-X8 resin, which produces a spherical resin bead containing paired anion and cation exchange sites. The result is a styrene divinylbenzene crosslinked, rigid polymer lattice with attached quaternary ammonium groups (strongly basic anion exchange groups), within which weaves a trapped, linear, relatively flexible acrylic polymer having carboxyl groups (weakly acidic cation exchange groups). Each resin bead is a molecular mixture of a cation and anion exchanger.

Larger volumes and special packaging for industrial applications are available on request.
