Quality Control

Our Lithium Hexafluoroantimonate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling, to ensure it meets high-purity standards suitable for electrochemical and catalytic applications. A Certificate of Analysis (COA) detailing purity, moisture content, and specific impurity levels is provided with every shipment to guarantee traceability and consistency.

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 under an inert atmosphere such as argon or nitrogen. Recommended long-term storage temperature is 2-8°C. The container should be kept tightly sealed in a desiccator when not in use to prevent degradation from atmospheric moisture.
