Quality Control

Our Iron Selenide is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification, inductively coupled plasma (ICP) for elemental assay and impurity profiling, and particle size analysis (PSA). A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment. We adhere to a strict quality management system to meet the precise requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its sensitivity to moisture and oxidation, it is recommended to handle and store this material under an inert atmosphere (e.g., argon or nitrogen) for long-term preservation of quality, especially for high-purity grades. Keep container tightly sealed when not in use.
