Quality Control

Our Tetraethenylgermane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and NMR spectroscopy to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and light-sensitive nature, store under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. Keep the container in a cool, dry, well-ventilated place, away from heat, sparks, and open flame.
