Quality Control

Our Calcium Bis(Fluorosulfonyl)Imide is produced under stringent conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including HPLC, NMR, and ICP-MS to control critical impurities such as moisture and metallic contaminants. A Certificate of Analysis (COA) detailing purity, assay, and specific test results is provided with every shipment to support your quality assurance protocols.

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, ideally under an inert atmosphere such as argon or nitrogen in a sealed container. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed in a dry environment to prevent degradation from atmospheric moisture.
