Quality Control

Our Lutetium Oxalate Tetrahydrate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise purity and compositional specifications. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, impurity profiles (including other rare earths), and loss on drying. Our quality commitment supports applications requiring high consistency and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). To prevent caking or decomposition, the container must be kept tightly sealed when not in use and stored in a low-humidity environment.
