Quality Control

Our Erbium Chloride Hydrate is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive quality documentation, including a detailed Certificate of Analysis (COA) for each lot, which specifies purity, assay, and impurity profiles. Our standard grades meet the requirements for research and industrial applications, with custom purity levels and analytical testing 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 hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and hydrolysis. For long-term storage, consider the use of a desiccator or inert atmosphere.
