Quality Control

Our 99.99% (4N) purity grade Magnesium Hydrogensulfate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and trace metal analysis by ICP-MS, to ensure it meets the exacting standards required for advanced industrial and research applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture and caking.
