Quality Control

Our Dysprosium Oxide is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We offer various grades, including 99.9% (3N), 99.99% (4N), and 99.999% (5N) purity, tailored to specific application requirements. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity and trace metal impurities as measured by ICP-OES/MS. Our quality commitment aligns with industry standards for high-performance materials.

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). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent absorption of water and carbon dioxide, which can affect product quality. For long-term storage, consider using desiccants or an inert atmosphere.
