Utility
Techniques for display and processing of mass spectral data
3 Aug 20
Processing mass spectral data may include performing one or more experiments using one or more samples, each experiment including mass analysis using a mass spectrometer; acquiring one or more raw mass spectral data sets as a result of performing the one or more experiments; receiving selection criteria; filtering the one or more raw mass spectral data sets in accordance with the selection criteria; and generating a chromatogram as a result of said filtering, wherein the chromatogram displays signal intensity as a function of scan time for a plurality of scan times and includes a non-zero signal intensity at each scan time only if, at the scan time, the selection criteria is met and otherwise the chromatogram includes a zero signal intensity at the scan time.
