Quality Control

Our Ammonia-15N is produced and handled under stringent conditions to ensure the highest isotopic and chemical purity. Each batch is analyzed to confirm isotopic enrichment and the absence of key impurities. Certificates of Analysis (COA) detailing isotopic purity, chemical assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature, store in a cool, well-ventilated area, away from heat and ignition sources. Cylinders must be secured in an upright position. Handle and store under appropriate pressure conditions as a compressed gas.
