Quality Control

Our Thulium Trihydroxide is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive analytical data, including trace metal analysis by ICP-MS/OES. A Certificate of Analysis (COA) detailing purity, physical characteristics, and impurity profiles is supplied with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, it is recommended to handle and store the material under a dry, inert atmosphere or in a desiccator to prevent moisture absorption and caking. Long-term storage should be in a dedicated chemical storage area at controlled room temperature (15-25°C).
