Quality Control

Our Holmium (III) Carbonate Hydrate is produced under a stringent quality management system. Each batch undergoes comprehensive analysis to verify identity, purity, and conformance to the declared 99.9% (REO) minimum holmium content. Standard testing includes Inductively Coupled Plasma (ICP) for assay and trace metal analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure full traceability and quality assurance for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place, ideally under controlled humidity conditions (e.g., in a desiccator). For long-term stability, store at room temperature (15-25°C) in a dedicated, well-ventilated area.
