Universal Gas Analyser from SRS

UGA Universal Gas Analyser

We are pleased to announce the introduction of the UGA Universal Gas Analyser from Stanford Research Systems.

The UGA builds on Stanford's well-known RGA Residual Gas Analyser and QMS Atmospheric Sampling System to provide users with a state-of-the-art bench top mass spectrometer that operates from above atmospheric pressure to UHV.

The UGA is ideal for on-line monitoring and analysis of gas mixtures. Whether you’re measuring trace-level contaminants, solvents, hydrocarbons, refrigerants or corrosive gases, the UGA analyzer is up to the task.
UGA Universal Gas Analyser direct UHV connection
  • Atmospheric pressure to UHV
  • 100, 200 and 300 amu systems
  • Fast response time (<0.2 s)
  • Electron multiplier std. on all systems
  • Stand-alone leak detection
  • Built-in heaters for bakeout to 120 °C
  • Windows software (RS-232 or Ethernet)
  • Turbo pump venting (opt.)
  • Multi-capillary inlet (opt.)

These analyzers are also simple to operate and maintain. The chassis design allows the instrument to be operated vertically or horizontally, and both front-panel and computer operation are supported.

The UGA system uses a two-stage pressure reducing inlet to sample gases at atmospheric pressure. After the pressure is reduced to around 10-6 Torr, the gas stream is sent to a mass spectrometer (residual gas analyzer - RGA) which measures the concentration of each mass of interest.

The UGA Windows software provides a graphical user interface for complex graphing and data analysis. The software also allows remote control of the system’s valves, heaters and pumps.

Typical Applications

  • Semiconductor exhaust gas monitoring
  • Glove box analysis
  • Fuel cell studies
  • Freon detection
  • Pollution monitoring
  • Fermentation studies
  • R&D vacuum analysis
