Chapter 3 Peak Detection and Labeling
Chromatogram
peak list
Spectrum peak list
3
The peak lists contain the following information.
Each entry represents one chromatographic peak in the trace and includes:
•Index, a sequential number assigned to each entry in the peak list
•Spectrum # or retention time (minutes), determined by the command selected from the Display menu
•Lower bound (spectrum # or minutes)
•Upper bound (spectrum # or minutes)
•Peak height (calculated relative to zero)
•Peak area (calculated relative to local baseline)
Each entry represents one spectral peak in the trace and includes:
•Index, a sequential number assigned to each entry in the peak list
•Centroid or Apex mass (reflects the Mass Type selected in the Peak Label dialog box)
•Lower bound (m/z)
•Upper bound (m/z)
•Charge (z)
•Peak height
•Relative intensity (calculated relative to zero, not to baseline)
•Peak area (calculated relative to local baseline)
