Quality Control

Our Germanium Tetraiodide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to ensure it meets the high-purity standards required for electronic and optical applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
