    Description

    Thermo Surveyor MSQ Plus RF/dc Prefilter Assembly.
    In good condition, came directly from mass spectrometer. Stored in a sealed environment to keep it dust free.
    Last image is a screenshot of the assembly from the manual.
    The RF/dc prefilter focuses the ions produced in the API source and transmits them to the mass analyzer. The RF/dc prefilter is a square array of square-profile rods that acts as an ion
    L transmission device and as a wide band-pass mass filter.
    During ion transmission, the offset voltage is positive for the positive ion polarity mode and negative for the negative ion polarity mode. Increasing the offset voltage increases the kinetic energy of the ions along the axis of the quadrupole through the differential aperture.  Allowable values for the RF lens bias are –10 V to +10 V. In the default Tune file (default.tune), the RF lens bias is set to 1.0 V. The default RF lens bias for the Autotune procedure is 0.5 V.
    Note: this is not a quadrupole analyzer.
