Quality Control

Our Carbon Monoxide (13C; 18O) is produced and handled under stringent conditions to ensure isotopic and chemical purity. Each batch is analyzed to confirm isotopic enrichment levels and the absence of significant gaseous impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic purity, chemical assay, and impurity profile is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed, appropriate pressure-rated cylinder or container, stored in a cool, well-ventilated area. Due to its highly volatile and gaseous nature, containers must be secured to prevent damage or tipping. Store away from heat, sparks, open flames, and incompatible materials. Cylinder temperature should not exceed 50°C (122°F).
