Ion Exchange Resins
Ion Exchange Resins
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.
