HP Data Explorer 4 Before calibrating

Voyager Data Examples

Before calibrating To optimize mass accuracy, do the following before calibrating:

1.	Display the spectrum of interest.
Baseline correcting 2.	From the Process menu, select Baseline Correction.
	The spectrum is baseline corrected. For more
	information, see Section 5.8.2, Using Baseline
	Correction.
Deisotoping 3.	From the Peaks menu, select Peak Deisotoping.	7
	The Deisotoping dialog box (Figure 7-14)is displayed.

4.For this example spectrum, specify H for Adduct and C6H5NO for Generic Formula.

5.Click OK.

Figure 7-15shows the baseline-corrected, deisotoped spectrum before calibration. For more information on deisotoping, see Section 3.4, Deisotoping a Spectrum.
