Quality Control

Our Erbium Oxide is produced under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards, typically ranging from 99.9% to 99.999% (3N to 5N), with trace metal impurities controlled to ppm levels. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical characteristics are provided with every shipment to guarantee batch-to-batch consistency and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept in a desiccated environment to prevent caking and degradation of purity.
