Quality Control

Our Amberlite CG-4B is manufactured under a strict quality management system. Each batch is tested to ensure it meets critical performance parameters such as total exchange capacity, moisture holding capacity, and particle size distribution. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee consistency and performance for your application.

Storage

Preserve in a tightly closed container, protected from light. This resin is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C). Ensure the original container is sealed when not in use to prevent moisture uptake and contamination. Do not allow the product to freeze.
