Quality Control

Our Niobium (IV) Sulfide is produced and tested under stringent quality management protocols. Each batch is analyzed to ensure it meets the specified 99.9% (Metals Basis) purity standard. Certificates of Analysis (COA) detailing trace metal impurities and physical characteristics are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere such as argon or nitrogen for long-term storage to prevent oxidation and degradation.
