Quality Control

Our Lithium Nonafluorobutanesulfonate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by ion chromatography or titration, impurity profiling, and moisture content determination, to ensure it meets high-purity standards suitable for electrochemical applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., argon or nitrogen) in a desiccator for long-term storage to prevent degradation.
