QuadraPure Metal Scavengers for GMP-Compliant Applications - Alfa Aesar

Johnson Matthey Scavenging Technologies QuadraPure™ polymer-based spherical scavengers offer cost-effective removal of precious metal catalyst residues for high purity products.

Advantageously, the very low levels of extractable impurities make QuadraPure™ products particularly suitable for GMP-compliant applications in both batch and continuous processing. Regulatory Support Files are available for each of the macroporous QuadraPure™ products to support their use in GMP-standard applications. The QuadraPure™ series can be used in loose resin bead format at R&D through to large-scale bulk process applications.
