Quality Control

Our Lithium Hydrogen Malate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling via techniques such as HPLC, titration, and ICP-MS to ensure high purity and batch-to-batch consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizing agents.
