Quality Control

Our Nitric Oxide is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each cylinder lot is analyzed to verify critical parameters such as assay purity and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, and we support compliance with relevant industry standards.

Storage

Preserve in a tightly closed, approved high-pressure cylinder or container, protected from light and stored in a cool, well-ventilated area. Due to its gaseous and easily oxidized nature, it must be stored under an inert atmosphere and kept away from heat, sparks, open flames, and incompatible materials such as flammable substances and strong reducing agents. Cylinder temperature should not exceed 50°C (122°F).
