Quality Control

Our Aluminum Selenide is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profile analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and strictly light-sensitive nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept in a secondary vessel to minimize exposure to moisture and air.
