Quality Control

Our Chloroplatinic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for platinum content, acidity, and impurity profiles. A Certificate of Analysis (COA) detailing assay results, typically determined by titration or ICP-OES, is provided with every shipment to guarantee consistency and traceability for your critical applications.

Storage

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