Quality Control

Our Discandium Triselenide is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and trace metal analysis, to meet the stringent requirements of research and advanced manufacturing. A Certificate of Analysis (COA) detailing purity, physical characteristics, and impurity profiles is provided with every shipment to guarantee product integrity and support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere such as argon or nitrogen to prevent oxidation and degradation. Keep away from strong acids and strong oxidizing agents.
