Quality Control

Our Praseodymium Chloride is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise purity and compositional specifications. A detailed Certificate of Analysis (COA) documenting assay, impurity profile, and physical characteristics is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored in a cool, dry place, ideally under an inert atmosphere or in a desiccator to prevent hydrolysis. Recommended storage temperature is 15-25°C.
