Quality Control

Our Aluminium Sulfide is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay and impurity profile analysis. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to guarantee it meets your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal humidity exposure. Store at room temperature (15-25°C) in a well-ventilated area, away from incompatible materials such as strong acids and moisture sources.
