  • Page 42: Ionizer

    Momentum Separation Two successive vacuum stages in the momentum separator (see Figure 1-8) reduce the pressure, causing further separation of the analyte particles from the vaporized solvent. The pressure reduction that occurs at the apertures between successive vacuum stages forces the aerosol-vapor mixture to expand and accelerates it toward the ionizer. About 90% of the solvent is carried off by the Stage 1 vacuum pump.

  • Page 53: Fixed Leak Assembly

    Pump Figure 1-20 View of the Vacuum Chamber Components 1.3.4 Fixed Leak Assembly The ThermaBeam Mass Detector has been designed with a fixed leak to prevent oil and solvent contaminants from entering the vacuum chamber. Background All oil-sealed mechanical vacuum pumps backstream oil to some extent. As the pressure falls and the oil becomes hot from the operation of the pump, oil vapors develop and work their way back up the vacuum tubing and into the vacuum chamber.
  • Page 54: Vent Valve

    Description The fixed leak is a stainless steel coiled tube and filter that allows a small amount of air to flow into the Stage 1 pumping line. This helps to prevent oil from backstreaming from the Stage 1 pump (Figure 1-21).

  • Page 58: Exhaust Trap Bucket

    1.3.8 Exhaust Trap Bucket The exhaust trap bucket (Figure 1-25) captures condensed solvent vapors and oil from the two vacuum pumps. This prevents solvent and oil from plugging the exhaust hoses. It is important to position the exhaust hoses so that condensation flows down into the bucket.
