Quality Control

Our Tetraisopropylgermanium is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity, critical for sensitive applications like semiconductor fabrication. Each lot is analyzed using advanced techniques including GC, NMR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile, hygroscopic, and easily oxidized nature, this material must be stored under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to minimize decomposition and volatility. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and acids.
