Quality Control

Our Perfluoropentane-1-Sulphonic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. Specifications are verified using advanced techniques including HPLC, NMR, and titration. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
