Quality Control

Our Arsenic Acid is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to relevant ISO standards, and each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical specifications. We are committed to meeting the stringent requirements of industrial and electronic grade applications.

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 hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C.
