Quality Control

Our Thulium Chloride is produced under stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. We employ advanced analytical techniques, including Inductively Coupled Plasma (ICP) and titration methods, to verify composition and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and physical characteristics is provided with each shipment to support your quality assurance and regulatory 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 with minimal humidity exposure. For long-term stability, store under an inert atmosphere such as argon or nitrogen in a desiccator. Recommended storage temperature is 15-25°C.
