Quality Control

Our Gadolinium157 is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and traceability. Each lot is analyzed for isotopic purity, chemical purity, and metallic impurities using advanced techniques like ICP-MS and GD-MS. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, confirming compliance with agreed 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). Due to its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., argon) is recommended to preserve purity. Keep away from incompatible materials.
