Quality Control

Our Bismuth Silver Sulfide is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot undergoes comprehensive analysis including phase purity verification by X-ray diffraction (XRD) and elemental composition analysis. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture.
