4.2 Creating anExtracted Ion Chromatogram

This section includes:

•Creating an Extracted Ion Chromatogram (XIC)

•Creating a Constant Neutral Loss (CNL) Chromatogram

You can create an extracted ion chromatogram:

•To improve the signal-to-noise ratio for a mass or mass range of interest

•To determine if mass differences in a data file correspond to loss of specific fragments by generating a Neutral Loss Chromatogram
