Quality Control

Our Ammonium Erbium(3+) Disulphate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profiling via ICP-OES, to ensure it meets the high-purity standards required for optical and electronic applications. A Certificate of Analysis (COA) detailing purity, trace metal content, and other critical parameters is provided with every shipment.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
