Quality Control

Our Carbonic Acid Calcium Salt (1:1), Hexahydrate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) are provided with every shipment, detailing results for key parameters such as assay, heavy metals, and loss on drying. We can supply material compliant with relevant standards including USP, FCC, and ACS grades upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide.
