Chromatograms
With chromatogram report items, you can print signals from the detectors of the chromatographic system on the report. The report item shows the results for all injections that are included in the selected data. There is at least one signal per injection. If the detector was configured to give multiple measurements, for example a diode-array or multi-wavelength detector, the chromatogram accordingly contains multiple signals per injection.
The data shown in the chromatogram also depends on whether the chromatogram is placed in a composite group and on the grouping and filtering of the composite group. |
Depending on the configuration of the report item, the signals may be shown in separate graphs, overlaid graphs, stacked graphs, or as Iso plots.

Example: chromatogram with three signals in separate graphs
Example: chromatogram with multiple signals in an overlaid graph
Example: chromatogram with multiple signals in a stacked graph
Example: chromatogram with multiple signals shown as iso plot
Chromatogram snippets
In the Report Items browser, different types of snippets are available for the chromatogram. For example:
The Single Signal Plot snippet always shows only one detector signal. The chromatogram is automatically repeated on the signal ID. Therefore, if the data contains multiple signals (for example, from multiple injections or from a multi-wavelength detector), the chromatogram is repeated several times.
The Multi Signal Plot snippets show all signals in the same chromatogram report item. You can configure the display format and group settings.
The Parameterized Chromatogram snippet shows a chromatogram with a fixed scaling that is specified in the Reports > Injection Report node of the processing method.
The Flowlayout snippets show a chromatogram embedded in a group that is repeated on compound ID. The Time axes of the chromatograms are automatically scaled to the corresponding peak begin and end times.
