Quality Control

Our Hexafluoroarsenic Acid is manufactured under stringent conditions to ensure high purity and batch-to-batch consistency. Quality is verified through a comprehensive suite of analytical techniques including titration, ion chromatography (IC), and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to meet the exacting standards of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and organic solvents. Due to its nature as a strong acid/organic solvent and highly volatile compound, containers must be kept tightly sealed and under an inert atmosphere if specified. Recommended storage temperature is 2-8°C to minimize volatility and degradation.
