Quality Control

Our Terbium(+3) Cation materials are produced and tested under stringent quality management systems. We offer various purity grades, including high-purity (≥99.9%, 99.99%, 99.999%) options tailored for specific applications. Quality is verified through advanced analytical techniques such as ICP-MS/OES for metallic impurity profiling and titration for assay determination. A comprehensive Certificate of Analysis (COA) detailing purity, impurity levels, and physical form is provided with each batch to ensure traceability and compliance with your specifications.

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) and must be handled under a dry, inert atmosphere (e.g., argon or nitrogen) to prevent oxidation or hydrolysis. Keep away from incompatible materials.
