Quality Control

Our protactinium products are produced and handled under stringent conditions to ensure the highest levels of purity and isotopic consistency for research purposes. All materials are subject to rigorous analytical verification, including mass spectrometry and γ-ray spectroscopy, to confirm identity and radionuclidic purity. A comprehensive Certificate of Analysis (COA) detailing isotopic composition, specific activity, and analytical methods is provided with each shipment to ensure traceability and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and propensity to be easily oxidized (store under inert atmosphere), this material must be stored in a dedicated, secure, and licensed facility for radioactive materials. Containers should be kept in a cool, dry, and well-ventilated area, away from incompatible substances. Strict adherence to all local, national, and international regulations for the storage of radioactive elements is mandatory.
