Quality Control

Our Mercuric Chromate is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) that document key parameters such as assay, heavy metal impurities, and moisture content. Our quality commitment ensures the material meets the stringent requirements for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its properties of being strictly light-sensitive, easily oxidized, and hygroscopic, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation and moisture absorption. Keep away from incompatible materials.
