Quality Control

Our Sodium Bis(Trifluoromethylsulfonyl)Imide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistent performance. We provide detailed Certificates of Analysis (COA) with key parameters including assay, anion content, moisture (KF), and trace metal analysis to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
