Minimal.
• Save minimal – only the compound level nodes are saved. No
spectra or compound chromatograms are saved. If you open
again, you will need to re-extract the complete result set.
• Save complete – all compound results are saved including
spectra and chromatograms.
• In this example, all the User Chromatograms, User Spectra and
Background Spectra are saved.
The Results File
47
MassHunter Webinar Series
• The results file is saved within
the data file as QualResult.bin.
• A copy of the qualitative analysis
method is also saved.
• Only one results file and method
can be saved.
• The results file is easily loaded
with the data file.
• Complete data archival.
