Quality Control

Our holmium is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality documentation, including detailed Certificates of Analysis (COA) that report key parameters such as purity and trace metal content. Our commitment to quality supports compliance with global standards for research and industrial applications.

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 pyrophoric nature in powder form, appropriate precautions must be taken to prevent contact with air and moisture. For long-term storage of bulk quantities, an inert atmosphere (argon) is recommended.
