Quality Control

Our Sodium Nitrate-15N is produced under stringent conditions to ensure high isotopic and chemical purity. Each batch is analyzed to confirm 15N enrichment levels and the absence of critical impurities. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and specific tests are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as combustible substances and strong reducing agents. Due to its hygroscopic nature, the container should be kept sealed under dry, inert conditions when not in use to prevent moisture absorption and caking.
