Quality Control

Our Terbium Acetate is produced and tested under a stringent quality management system. We provide material with typical purities of 99.9% (3N) to 99.99% (4N) on a rare earth oxide basis, tailored to application requirements. Each batch is analyzed for terbium content and key metallic impurities. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept sealed under dry, inert conditions when not in use to prevent moisture absorption and caking. Long-term storage is recommended at controlled room temperature (15-25°C).
