Quality Control

Our Phosphorus Trisulfide is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure it meets defined purity and compositional standards. A Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Recommended storage temperature is 15-25°C.
