Quality Control

Our Amberlite CG-400 is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets consistent performance specifications for total exchange capacity, moisture content, particle size distribution, and chloride form uniformity. Certificates of Analysis (COA) documenting these parameters 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 at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture uptake, which can affect performance. Keep away from incompatible materials such as strong oxidizing agents.
