Quality Control

Our Yttrium Selenide is produced and handled under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including purity assay and impurity profiling via techniques like X-ray diffraction (XRD) and inductively coupled plasma (ICP) analysis. Certificates of Analysis (COA) detailing specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation. Recommended long-term storage temperature is 15-25°C.
