Depending on analytical applications, GAOS MS process mass spectrometers are equipped with various modifications of the sample preparation system.


Sample preparation system specification:


  • Continuous sampling of the gas probe under conditions:

             Temperature up to 1200 °C;             
             Dust content up to 30 g/m3
             Pressure (10-3÷3) bar; 
             Presence of a condensate, aggressive gases; 

  • Step-by-step cleaning of the gas probe, removal of dust, condensate, cooling;
  • Switching from different sampling points and transporting the gas probe to the mass spectrometer input;
  • Automatic control of operating parameters (temperature, pressure, volume flow) and self- diagnosis of the sample conditioning system.
