Quality Control

Our Tetramethylammonium Carbonate solution is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the 99.99% purity specification and is free from critical metallic contaminants. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from heat sources and incompatible materials such as strong acids. The solution is hygroscopic; ensure containers are properly sealed after use to prevent moisture absorption and potential decomposition.
