Inerting, blanketing and purging
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.
We supply pure gases and gas mixtures in a range of volumes to meet your needs. Multi-compendial nitrogen meeting the monograph specifications of the three major pharmacopoeias (USP-NF, Ph. Eur., and JP) is available in certain locations.
Air Liquide provides engineering support including modeling, sizing, consumption estimates, and equipment recommendations. We also assist with initial removal of impurities. We can perform tank farm inerting audits to help you maintain an inert environment. Our iDATAL web-based gas management telemetry system provides you with an accurate, easy-to-use and cost-effective means of tracking your cylinder gas usage. In addition, we provide gas handling safety expertise and a range of resources, including Certificates of Analysis (CoA) upon request.
Developed to support product quality and process safety, Air Liquide’s VESTAL™ system helps to protect liquid products from impurities found in the air and reduces the potential for corrosion in tanks and vessels.
