Ion Exchanges Resins for Research and Development - Alfa Aesar

Alfa Aesar is proud to offer an extensive line of ion exchange resins. Our decades of experience in offering these resins gives us the knowledge you need to proceed with your research and development.

We offer the following types of resins:

Gel –Type resins:

The gel-type resins of the styrene-DVB [poly(styrene-divinylbenzene)] type date back to 1947. These materials do not contain any true porosity. Ions to be exchanged must diffuse through the gel structure to the exchange sites. The intermolecular distances which will limit the size of the ion that can migrate through the gel is often referred to as the apparent porosity. Even in low crosslinked gel-type resins, the apparent porosity is usually no greater than 40 Angstroms.

Macroreticular resins:

The first macroreticular resin was placed into service in 1959. These resins can best be described by comparing them with a small ball of tough rigid sponge having large discrete pores. An average pore of 1300 Angstroms is not unusual. Macroreticular resins offer a number of advantages over the conventional gel-type resins. First of all, the large pores mean that high molecular weight ions can be more completely removed from solution and more completely eluted from the solution on regeneration than would be the case with other materials. Secondly, the open structure of the macroreticular resins permits the use of tough copolymers which would be too dense to effectively act as ion exchange resins if they were used in a strictly gel-type system. Although the macroreticular resins, on the whole, do have a somewhat lower capacity than the gel-type resins, this is often offset by the longer operating life of the macroreticular resins or the that they will effect removals not possible by the gel-type resins.

We offer the following types of gel-type and macroreticular resins:

  • Cation and Anion exchange resins
    • Strongly acidic - Sulfonic acid functionality - Amberlite® IR, Diaion® SK, PK, UBK
    • Weakly acidic - Carboxylic acid functionality - Amberlite® IRC, Diaion® WK
    • Strongly basic - Quarternary Ammonium functionality - Amberlite® IRA, Diaion® SA, UBA
    • Weakly basic - Tertiaryamine functionality - Amberlite® IRA
    • Nuclear Grade - Amberlite® IRN - for treating water in the nuclear power industry, minimizing corrosion
    • Chelating resin - Diaion® CR - capture metal ions by chelation with the respective amine functionality
