Quality Control

Our Cesium Heptafluoroniobate, 99.99% is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling via ICP-MS, to ensure it meets the specified 4N high-purity standard. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity levels is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place, ideally under an inert atmosphere or in a desiccator to prevent hydrolysis. Recommended long-term storage temperature is 15-25°C. Keep the container tightly sealed when not in use.
