Prerequisites
To be able to carry out the procedure as described, you need the privilege Processing Method > Edit spectrum extraction parameters. Privileges are configured in the Control Panel.
If the project enforces method approval, the method status must be Generic. For details, see Method approval.
In the Processing Method window, select the Extraction > Spectrum node and the MS tab.
Under Automatic spectrum extraction, select the Extract spectra from integrated peaks on reprocessing check box. Choose for which peaks you want to extract spectra:
Identified Peaks: Spectra are extracted from an MS chromatogram using the peaks listed in the compound table.
All Peaks: Spectra are extracted for all peaks of an MS chromatogram.
Under Peak spectra, choose a Spectrum type (e.g. Peak apex spectrum) and a Background mode for the selected spectrum type.
Background spectra will be subtracted corresponding to this setting.
Reprocess the data.
Extracted spectra will be shown in the MS Spectrum window, and listed under the details for each individual injection in the injection tree.
