Quality Control

Our Lithium 1,1,2,2,3,3-Hexafluoropropane-1,3-Disulfonimide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, Karl Fischer titration, and ICP-MS, to ensure high purity and minimal trace metal content. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee consistency and compliance with your R&D and manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place, preferably under an inert atmosphere such as argon or nitrogen. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to prevent moisture condensation.
