Quality Control

Our Indium Selenide is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high chemical purity and consistency, meeting the stringent requirements of advanced material applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and trace metal content is provided with every shipment and is available upon request.

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 moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., argon or nitrogen) for long-term storage to prevent oxidation and degradation.
