Mass Trace
Contrary to original TIC or SIM chromatograms that are recorded during data acquisition, a mass trace is an MS chromatogram for a specific mass area. Mass traces can be extracted from a Mass Spectrum and saved as a new channel. This is possible online during data acquisition but can be done later as well.
