Quality Control

Our Lithium Diisopropylnaphthalenesulphonate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and identification by FT-IR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to guarantee compliance with your specifications and industry standards.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from heat sources and incompatible materials.
