Nitrogen Generator for for LC-MS / LC-MS-MS (PSA Technology)

  • Nitrogen Generator produces a continuous flow of high purity Nitrogen at selected pressure.
  • The modular pressure swing adsorption (PSA) unit operates with alternating pressure increase and decrease.
  • Untreated air flows under pressure through the reaction towers containing carbon molecular sieves adsorber. Moisture, CO, CO2, THC, O2 and other unwanted components in the air are adsorbed, leaving Nitrogen Gas of required purity.
  • During the desorption cycle, the trapped substances adsorbed are released again at low pressure and the adsorber is ready for next cycle.
  • Flow range available from 10 LPM to 30 LPM and above.
  • Microcontroller digital display
