Quality Control

Our Erbium (III) Iodide is produced and handled under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a suite of analytical techniques including inductively coupled plasma (ICP) analysis, X-ray diffraction (XRD), and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and trace metal content is provided with each shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation.
