Quality Control

Our Aluminon is manufactured under a strict quality management system. Each batch is tested to ensure high purity, consistent performance, and compliance with analytical reagent grade specifications. Key parameters include identity confirmation by IR spectroscopy, assay by titration, and control of moisture content. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture, which may affect performance.
