Quality Control

Our Coppergalliumselenide is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high material performance. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as purity, phase composition, and elemental stoichiometry. Quality is verified through techniques including X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and inductively coupled plasma (ICP) analysis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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) when appropriate to prevent oxidation and degradation.
