Quality Control

Our Calcium Iodide is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity and composition. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, heavy metal content, and loss on drying. We can supply material compliant with various pharmacopeial standards (e.g., USP/EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C). The container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and degradation. Store away from incompatible materials such as strong acids and strong oxidizing agents.
