Quality Control

Our Holmium(+3) Cation is produced and handled under stringent quality management protocols. Each batch is subjected to rigorous analytical testing, including inductively coupled plasma mass spectrometry (ICP-MS) and ion chromatography, to ensure exceptional purity and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, cationic purity, and trace metal impurities is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the material must be stored in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen to prevent moisture absorption and oxidation. Recommended long-term storage temperature is 15-25°C.
