Quality Control

Our Gadolinium Hydroxide Hydrate is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed for critical parameters including gadolinium content, impurity profiles (other rare earth elements), and loss on ignition. A comprehensive Certificate of Analysis (COA) detailing these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong acids.
