Quality Control

Our Manganese(II) Carbonate Hydrate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the required specifications for purity, heavy metal content, and physical properties. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of moisture from the air, which can affect product quality and handling. Recommended storage temperature is 15-25°C.
