Quality Control

Our Samarium-154 is produced and handled under stringent quality management protocols. Each batch is characterized for isotopic abundance and chemical purity using advanced analytical techniques including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Glow Discharge Mass Spectrometry (GDMS). A comprehensive Certificate of Analysis (COA) detailing isotopic composition, metallic impurities, and other critical parameters is provided with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). For long-term storage of the metal form, consider storage under an inert atmosphere such as argon to minimize surface oxidation. Keep away from strong acids and strong oxidizing agents.
