Select a step where Air Liquide intervenes in your value chain.




Raw materials, intermediate products, APIs, and excipients may be sensitive to the oxygen and moisture present in atmospheric air. Thus, they often need to be protected with an inert gas to avoid undesirable reactions and maintain drug efficacy. Nitrogen inerting, blanketing and purging also help to mitigate ignition and explosion risks during the storage of flammable solvents, powder milling and pneumatic transfer. Our inerting solutions come with engineering support and provide optimized nitrogen consumption and accurate monitoring, minimizing product degradation and safety risks while reducing operating costs.



Air Liquide provides engineering support including sizing, consumption estimates, and equipment recommendations. We can perform tank inerting audits to help you maintain an inert environment. We provide gas handling safety expertise and a range of resources, including Certificates of Analysis (CoA) upon request.
