Report Tables
The Peak Summary Report

Commonly used reports such as the  Integration Report and the  Calibration Report contain data of one sample only. In case of a chromatogram comparison, only the data of the selected (active) chromatogram is displayed.

Comparing peak data from different samples is possible via the (peak) Summary report table.

Sample Selection

• If one sample is selected and opened from the Browser, the peak summary is based on the corresponding Sequence.

• If several samples are selected in the Browser, these selected samples only will be part of the Summary report table.

• If a Query is started in the Browser, the search result forms the basis for the Summary. In this way, it is possible to compare peaks from different sequences.

Peak Selection

• Normally, no peak is selected in the chromatogram of the sample. The Peak Summary Report therefore contains no entries. All fields are marked n.a. (not available) or Div/0 (Division/0)., The Peak Summary Table receives entries only when a peak is selected manually within a chromatogram. As soon as this is performed, this peak is searched in all previously selected samples. The search result is displayed in the Summary Report.

• For each Peak Summary column, it is possible to define whether the values of the currently selected (Selected Peak) or one specific peak (Fixed Peak) are displayed. Access these options by selecting Column Properties on the context menu.

• If the currently selected peak is an identified peak, that is, if the peak is labeled with its name in the peak table, all involved samples are searched for this peak name. The corresponding values of all found peaks are displayed in the Summary.

• If the currently selected peak is a non-identified peak, that is, if the peak is not labeled with its name in the peak table, a "fixed time window" (± 2.5% of the detected retention time) is calculated for this peak. This calculated time window appears in the header instead of the peak name. If two or more peaks are detected in the time window, the peak that is nearest to the specified retention time will be selected.

Creating a Summary

• Double-click one of the samples to open the Integration window.

• Display the Report and select the default Summary worksheet available in Chromeleon. It contains a selection of the most important default Peak Variables. For each sample that is part of the Summary, a separate line is reserved in the report.

• If the default Summary Report is not available, a new worksheet can be defined. Proceed as described in: Creating and Using Report Tables  Adding and/or Renaming a Worksheet.

The sample that is currently selected in the chromatogram window is highlighted in the Summary Table.
