Quality Control

Our Rheniumoxide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by titration and impurity profiling via ICP-MS, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing purity, physical characteristics, and trace metal content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent moisture absorption and degradation. Isolate from incompatible materials such as strong acids and organic solvents.
