Quality Control

Our Perfluoro(2-Ethoxyethane)Sulfonic Acid is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity (by titration or NMR), assay, and impurity profiles is provided with every shipment. We adhere to relevant industry standards and can support customer-specific quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) and strong acid nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
