Quality Control

Our Hexafluoroarsenic Acid is manufactured under stringent controls to ensure high purity and batch-to-batch consistency, meeting the exacting requirements of advanced industrial applications. Quality is verified through comprehensive 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 guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area dedicated to corrosive and moisture-sensitive materials. Due to its nature as a strong acid/organic solvent and fluoride/strong alkali, it must be kept separate from incompatible substances. Containers should be kept tightly sealed when not in use to minimize exposure to atmospheric moisture and to control high volatility.
