Quality Control

Our Hexafluorophosphate is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including HPLC, ion chromatography (IC), and titration. A Certificate of Analysis (COA) detailing purity, anion content, and impurity profiles is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
