Quality Control

Every batch of our palladium catalyst undergoes rigorous quality testing to ensure consistency and high catalytic activity. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing purity, metal content, and spectroscopic identification. Our quality management system is designed to meet the stringent requirements of cGMP and ISO 9001 standards for traceability and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry place. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air and moisture should be avoided to maintain catalytic activity.
