Quality Control

Our Meta-Arsenic Acid is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and conformance to agreed specifications, which typically include assay by titration and limits for key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to relevant industrial quality standards and can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and reducing agents. Due to its nature as a strong acid, containers should be kept in a dedicated corrosive materials cabinet. Recommended long-term storage temperature is 15-25°C.
