7.2.2 Processing Before Calibrating to
Optimize Mass Accuracy
This section includes:
• Calibrating without baseline correcting and deisotoping
• Before calibrating
• Calibrating
Calibrating
without baseline
correcting and
deisotoping
For optimum mass accuracy, baseline correct and deisotope a
spectrum before calibrating.
Figure 7-12 shows a spectrum before calibration.
Figure 7-12 Spectrum Before Calibration
Figure 7-13 shows a spectrum that has been calibrated
without initial baseline correction and deisotoping. Mass
accuracy is not acceptable.
