Fragment Match Spectrum view parameters

Parameter

Description

Header

Displays the following:

  • Name and path of the raw data file
  • Numbers of any grouped spectra
  • Retention time of the precursor ion, in minutes
  • Type of mass spectrometer used to create the data in the raw data file
  • Fragmentation method used
  • Charge state of the precursor ion
  • Mass-to-charge ratio (m/z) of the precursor ion, in daltons
  • MH+ (the protonated monoisotopic mass), in daltons

Red vertical lines

a-, b-, and c-series ions matched in the spectrum.

Blue vertical lines

x-, y-, and z-series ions matched in the spectrum.

Intensity (counts) (y axis)

Displays the scale of the intensity of the product ions.

m/z (x axis)

Displays the mass-to-charge ratio of the product ions, in daltons.
