Capillary GC Columns | Nitrogen Gas Generators

  Atmospheric air comprises seventy-eight percent of nitrogen, twenty-one percent of oxygen, and one percent of other gases. Nitrogen finds its use in various industries like food packaging and mining. These industries require a constant supply of nitrogen. Some industries use nitrogen cylinders, but these cylinders are not easy to transport and are expensive.   Industries use on-site nitrogen gas generators to meet their nitrogen supplies. Nitrogen generators produce pure nitrogen by separating it from oxygen and other gas molecules. Types of nitrogen gas generators Following are the two types of nitrogen gas generators : Pressure Swing Absorption (PSA) nitrogen generator - This method uses compressed air to get nitrogen. This method consists of two vessels. The first vessel contains carbon molecular sieves that absorb oxygen. The other chamber depressurizes nitrogen which flows to the storage unit. The nitrogen thus formed is of high purity. Membrane nitrogen generator -
