6. Select the method to use for calculation:
• Automatic—Selects additional multiply
charged peaks based on the selected peaks
and performs the calculation.
NOTE: If the trace is noisy, the software may not
accurately select additional multiply charged
peaks.
• Manual—Performs the calculation using only
selected peaks. Does not select additional
multiply charged peaks.
7. Select Apex or Centroid mass to use for the calculation.
8. Enter the mass/charge range to include in the calculation.
This range is used for two purposes:
• If you selected Automatic mode, the software
searches this range for other peaks that are in the
same charge series as the peaks selected above.
The software includes these other peaks in the
calculation, to improve signal-to-noise ratio and
the accuracy of the calculation.
• Regardless of mode, the software uses all data
points in this range to construct the deconvoluted
spectrum.
9. Select or enter the mass of the adduct ion to use in the
calculation. The mass of a proton (H
+
) is selected by
default.
10. To display both the zero-charge spectrum trace and the
deconvolution results, select Generate Zero-Charge
Spectrum.
To display only the deconvolution results, do not select
Generate Zero-Charge Spectrum.
