Quality Control

Our Sodium Bis(Nonafluorobutanesulfonyl)Imide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, anion/cation content, moisture, and trace metal impurities is provided with every shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption. Recommended long-term storage temperature is 2-8°C. The container should be kept tightly sealed when not in use.
