Working with Detected Components

Detected components are marked with a triangle in the original chromatogram. Because the program calculates the precise retention time (tR) of each component the component triangle can appear between scan points.

 

Note:

To display a deconvoluted spectrum of a component rather than of a scan, click the triangle that marks the detected component in the chromatogram pane. To display an original scan at the position of a detected component, you should click above the triangle.

 

 

If you select a component by clicking its triangle, a deconvoluted spectrum will appear in the spectrum pane. This spectrum can be processed in the same way as any spectra in the program, e.g. searched in a library or copied to Database Manager.

If you move the mouse cursor over a component triangle, a tool tip rectangle will inform you about the component number, precise retention time and model ion m/z value that were used in the automated detection and deconvolution processes.

 

Chromatographic components can be edited or searched in Components Editor that can be opened using Edit Components    button.

 

To copy or process more than one detected component in Database Manager or in Spectra Classifier modules, you must first select them.

To select one or more components:

  • Click on the Select Scans or Components button image\ButGCLCMSSelComp.gif and select the desired components with the mouse cursor while holding down the LEFT mouse button

 

To select all detected components in a run:

  1. Click anywhere in the chromatogram pane with the RIGHT mouse button and a pop-up menu will appear.

  2. Click on the Select All menu item.

 

The program makes a strict distinction between original scans and detected components and does not mix them. When selecting a chromatographic region, components are preferred over scans. If you select a chromatographic region that contains components, only these components will be selected. If you select a region that does not contain any components, all scans in that region will be selected.
