Quality Control

Every batch of Tellurium125 is produced and verified under a strict quality management system. We employ advanced analytical techniques, including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Glow Discharge Mass Spectrometry (GDMS), to guarantee isotopic enrichment and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic abundance, elemental impurities, and physical form is provided with each shipment to ensure traceability and compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store this material under an inert atmosphere (e.g., argon or nitrogen) for long-term preservation. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
