*   Processing Data-Reduced Chromatograms
Library storage of data-reduced chromatograms is not a replacement for the standard certified archiving procedures that the FDA (21 CFR Part 11) requires, but rather an accompaniment to them.
v
To import a data-reduced chromatogram from the Chromatogram Processor
1.
In the Chromatogram Processor, right-click any of the panes and choose Copy > Copy Chromatogram from the shortcut menu.
For detailed information about using the Chromatogram Processor module, see Chromatogram Processor Module.
2.
3.
Right-click and choose Paste > Chromatogram from the shortcut menu.
The application adds the chromatogram to the tree and replaces the Spectrum tab with a Chromatogram tab.
Chromatograms are highlighted in blue in the Spectral Tree to easily distinguish them from other records.
You can save data-reduced chromatograms in the Database Manager window to any library using the same procedure as for saving spectra or trees.
v
To edit or search components in data-reduced chromatograms
1.
In the Chromatogram Processor, click the Components Editor button, .
Note  This feature is enabled only after you have generated components by using one of the Components Detection and Spectra Deconvolution features in the Chromatogram Processor.
The Components Editor window opens.
2.
a.
Choose Search > Tree from the Mass Frontier main menu.
The Library Search dialog box opens.
b.
c.
For additional information about the Library Search parameters, see Spectral Tree Search.
3.
a.
Choose Search > Tree from the Mass Frontier main menu.
The Library Search dialog box opens.
b.
c.
Click the Advanced tab.
d.
In the Search In area, select the Chromatograms check box.
e.
v
To preview a chromatogram in the Chromatogram Processor window
1.
2.
Click the Chromatogram Processor button, , in the Database Manager toolbar.
The Chromatogram Database Viewer opens.
The application recalls the file path to the original chromatographic data for every chromatographic library entry.
3.
v
To access the original chromatographic data set
1.
2.
Click the Chromatogram Processor button, , in the Database Manager toolbar.
The Chromatogram Database Viewer opens.
3.
Click the Reload Original Data File button, , in the Chromatogram Database Viewer toolbar.
The original data opens in a new Chromatogram Processor window.
