Quality Control

Our Boron Sulfide is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

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 sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Recommended storage temperature is 15-25°C.
