Quality Control

Our Ammonium Polysulfide is manufactured under strict process controls to ensure batch-to-batch consistency and reliability. Quality is verified through a series of analytical tests including assay, sulfur content analysis, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Due to its properties, the solution should be kept at temperatures between 15-25°C and protected from freezing. Keep container tightly sealed when not in use to minimize volatilization and moisture absorption.
