Quality Control

Our Aluminum Arsenide 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 specific results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent moisture absorption and degradation. Store away from incompatible materials.
