Quality Control

Our Germanium(II) Iodide is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity and assay specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere such as argon or nitrogen to prevent degradation.
