The types and uses of process gases in drug delivery preparation and pharmaceutical manufacturing are many and varied. The virtually inert attributes of nitrogen make it suitable for blanketing and purging, while hydrogen, zero-air, TOC-free air, along with nitrogen all find uses within manufacturing process quality laboratories. Today it is possible to generate all of these gases on-site using standalone gas generators.
Applications of High Purity Gases in Drug Delivery and Manufacturing
The diversity of applications for high purity gases within pharmaceutical manufacturing is extremely wide-ranging. It is worthwhile mentioning some of the most common. Blanketing with nitrogen is an important process used to protect volatile substances, which react with oxygen or water vapour. By surrounding the substance with a protective layer of dry, inert gas, the stability of the substance can be maintained without any degradation. Controlled flow may be used to preserve the density of the nitrogen blanket. Purging involves the flushing of a vessel with nitrogen to dispel oxygen and moisture, usually at process start-up or shutdown.
