Quality Control

Every batch of our isotopically labeled nitric acid is produced and tested under stringent conditions to ensure exceptional isotopic and chemical purity. Quality is verified through advanced analytical techniques including Isotope Ratio Mass Spectrometry (IRMS) and titration. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing the isotopic enrichment (Atom %), assay, and impurity profile to meet the exacting requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area, away from incompatible materials such as organic compounds, strong reducing agents, and bases. Due to its nature as a strong acid and oxidizer, ensure containers are clearly labeled and made of compatible materials (e.g., fluoropolymer). Recommended storage temperature: 15-25°C.
