Chapter 3 Peak Detection and Labeling

3.1 Overview

This section includes:

•Default peak detection

•The resolution-based peak detection routine

3.1.1Default Peak Detection

Overview When you open a data file, it is automatically peak detected.

For:

 

• Chromatographic data— The software uses default

 

 

settings that have been optimized to yield acceptable

 

peak detection for many sample types. For more

3

information, see Section 3.7, Default Peak Detection

Settings.

• Spectral data— The software uses a resolution-based

 

 

peak detection routine to calculate peak detection values

 

that provide optimum peak detection for most sample

 

types. For more information, see Section 3.1.2, The

 

Resolution-Based Peak Detection Routine.

 

For many applications, the default peak detection settings and

 

settings calculated by the resolution-based peak detection

 

routine provide acceptable peak detection. If default settings

 

do not provide acceptable peak detection, you can adjust the

 

settings as described in:

 

• Section 3.2.1, Strategy for Mariner Peak Detection

 

• Section 3.2.2, Strategy for Voyager Peak Detection

NOTE: If peak detection settings do not detect desired peaks, you can manually insert peaks. See Section 3.3.2, Inserting Peaks in the Peak List.
