Quality Control

Our Copper(I) Sulphite Monohydrate is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for assay, impurity profiles, and physical parameters is provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after opening to minimize exposure to moisture and air. For long-term storage, consider an inert atmosphere.
