  • Masslynx 4.2
  • LCMS system
  • Mass spectrometer

Lost communication with the mass spectrometer

FIX or WORKAROUND

  1. If you have a Quad instrument, follow WKB25175 to perform a full reboot.
  2. If you have a QTOF instrument, follow wkb300724 (instructions below) to perform a full reboot.
  3. If the full reboot restores communication, Masslynx message "Instrument not present" will change to "Not scanning". If it does not, suspect the EPC has failed.
