Quality Control

Our Disamarium Selenide is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analysis to ensure consistency and high purity, meeting the exacting standards required for research and industrial applications. Certificates of Analysis (COA) detailing purity, metallic impurities, and phase identification are available upon request.

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 nature of being easily oxidized, long-term storage under an inert atmosphere (argon or nitrogen) is recommended to maintain product integrity. Keep away from incompatible materials such as strong acids and oxidizing agents.
