Quality Control

Our Gadolinium Oxide is produced under stringent quality management protocols. We offer various purity grades, including 99.9% (3N), 99.99% (4N), and 99.999% (5N), tailored to specific application requirements. Each batch is analyzed for trace metallic impurities and physical characteristics. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to ensure compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. For long-term storage of high-purity grades, consider desiccated or inert atmosphere conditions to prevent moisture absorption and maintain product integrity.
