Quality Control

Our Calcium Chromate(Vi) is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and reliability. The product is tested against relevant industry specifications, with key parameters including purity, heavy metal content, and insolubles. A Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term stability. Keep container tightly sealed when not in use to minimize exposure to moisture and air.
