Quality Control

Our Chromate(5-) potassium sodium complex is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet exacting specifications. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and heavy metal content 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and degradation.
