Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production is monitored against strict in-process controls for key parameters such as ionic capacity, moisture content, and particle size distribution where applicable. Certificates of Analysis (COA) detailing lot-specific results are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
