Quality Control

Our Ammonium Nitrate-15N is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity. Each batch undergoes rigorous analytical testing, including Isotopic Enrichment Analysis by Mass Spectrometry, Chemical Purity Assay, and verification of critical impurities. Certificates of Analysis (COA) detailing the specific 15N atom percent enrichment, chemical assay, and impurity profile are provided with every shipment to guarantee consistency and reliability for your sensitive applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its hygroscopic (moisture-sensitive) and strong oxidizing properties, it must be kept separate from combustible materials, reducing agents, and acids. Recommended storage temperature is 15-25°C.
