Quality Control

Every batch of our Germanium Arsenic Pieces is produced and tested to meet the stringent requirements of advanced materials research. We guarantee a minimum purity of 99.999% (5N) on a metals basis, verified through advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing trace metallic impurities is provided with each shipment to ensure full traceability and compliance with your internal quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive; keep the container tightly sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent surface oxidation. Isolate from strong acids and strong oxidizing agents.
