Quality Control

Our Diammonium Erbium Pentanitrate is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay (Er2O3 content), nitrate content, and trace metal impurities. Our quality commitment aligns with general industrial and research-grade standards.

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 hygroscopic and strong oxidizing nature, the container must be kept tightly sealed in a dry environment and segregated from combustible materials, reducing agents, and strong acids. Recommended storage temperature is 15-25°C.
