Quality Control

Our Lithium Bis(Trifluoromethanesulphonyl)Imide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and ICP-MS for trace metal content, to ensure it meets the exacting standards required for electrochemical applications. Certificates of Analysis (COA) detailing all specification parameters are available upon request.

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, ideally under an inert atmosphere such as argon or nitrogen in a desiccator. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
