Description: The single quadrupole compact mass spectrometer (CMS) by Advion offers polarity switching in a single analysis for a greater range of detectable ions. –L indicates a device specification for larger molecules (up to 2000 g/mol). The device provides electrospray ionization (ESI) and atmospheric pressure interface ionization (APCI). The device is very compact and enables to record mass spectra on the fly, with measuring times of about 10 seconds per measurement.


  • ESI and APCI ionization sources with polarity switching
  • Quadrupole mass filter (single)
  • Electron multiplier Detector with high energy conversion dynode detector
  • Ions detectable up to 2000 g/mol
