Quality Control

Our Sulfide ((Sx)2-) products are manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Due to its reactivity, it is recommended to store under an inert atmosphere if in a purified form. Keep container tightly sealed when not in use to minimize moisture absorption and decomposition.
