Hybrid Amphoteric Ion Exchange Media, Sodium & Hydroxide Forms
See DetailsResinTech SIR-2000 is a gel strongly basic anion resin that also has weakly acidic functionality. Its amphoteric nature results from the resin’s two opposing functional groups – strong base anion & weak acid cation – which are interwoven and self-absorbed within the polymer structure of each resin bead. SIR-2000 is well-suited for chromatographic separation processes that require ion retardation, and can also be used to remove salts from organic solutions.
