6.5.2 Calculating Mass Resolution
You can calculate mass resolution for up to four peaks in the
spectrum currently being acquired. The resolution values are
displayed in the trace next to the mass value for the peak.
Calculating
resolution for live
data
To calculate mass resolution:
1. When acquisition is complete, select the Current
spectrum.
2. From the Tools menu, select Resolution Calculator.
3. In the Resolution Calculator dialog box (Figure 6-12), set
the percentage of peak height at which to calculate
resolution. The default is 50%, which calculates the
resolution at the full width/half maximum of the peak
height (FWHM).
NOTE: Measuring resolution at the full width/half
maximum is the industry standard. Use 50% Peak
Height for most applications.
4. Set Minimum Peak Intensity. Signals below this intensity
(absolute counts) are not included in the calculation.
