To create an extracted ion chromatogram for a mass range
from the Spectrum window:
1. Click the Chromatogram window to activate it.
2. Select Duplicate Active Trace from the Display menu to
keep the original data displayed after processing.
3. In the Spectrum window, right-click-drag over the mass
region of interest in the extracted ion chromatogram. The
width of the box you draw defines the precise mass range
used in the extracted ion chromatogram.
The extracted ion chromatogram is displayed in the
Chromatogram window (Figure 4-2) with the mass
range indicated in the trace label.
