Quality Control

Every batch of our Sulfur Dioxide Mixed With Ozone (1:1) is manufactured and analyzed under stringent conditions to ensure precise molar ratio consistency, high purity, and reliable performance. We employ advanced gas chromatography (GC) and spectroscopic methods for accurate composition verification. A comprehensive Certificate of Analysis (COA) detailing purity, composition, and critical impurities is provided with each shipment, ensuring full traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed, specially designed cylinder or container, protected from light and heat sources. Store in a cool, well-ventilated area dedicated for oxidizing gases, away from combustible materials, reducing agents, and moisture. Cylinders must be securely fastened and stored upright. The storage area temperature should be maintained below 30°C (86°F). Due to the reactive and gaseous nature of this mixture, refer to the Safety Data Sheet (SDS) for complete handling and storage protocols.
