7.1.2 Deconvoluting and
Evaluating Unresolved
Chromatographic Peaks
Overview You can use the Data Explorer software to deconvolute
chromatographic peaks and obtain masses for each
component by:
Creating a combined spectrum to identify the coeluting
species by mass
Creating extracted ion chromatograms for the masses,
and comparing the extracted ion chromatograms to the
original TIC containing the unresolved peaks
You can then create a combined spectrum from each
extracted ion chromatogram to evaluate the spectral data.
Creating a
combined
spectrum
The following example illustrates how to deconvolute two
unresolved chromatographic peaks in a tryptic digest of
cytochrome c:
1. Display the data file.
2. In the Chromatogram window, zoom in on the unresolved
peaks (Figure 7-2).
Figure 7-2 Unresolved Peaks in Cytochrome C
3. In the Chromatogram window, right-click-drag over the
unresolved peak pair.
