Next add the proper ppm shift value as shown in the image and click submit.

This mass corrector will shift precursor masses in MS2 and peaks in MS1 spectra.

  • e.g. -3 shifts peaks by -3 ppm
  • e.g. 10 increases masses by 10 ppm
  • It is recommended to check the Delta Mass Plotter after the search to observe delta mass distribution.
