Chromatograms

If you installed the 2D-LC Add-on, the Chromatograms window contains more information. See 2D-LC help on chromatograms for details.

Chromatograms

This window shows the chromatograms of the selected samples. If you did not pin any injections in the injection tree, only the chromatogram of the focused injection is shown. If you pin several injections in the injection tree, you can compare multiple chromatograms with the focused injection. The way multiple chromatograms are displayed depends on the selected display mode.

Peak annotations

Identified compounds are labeled with their compound names and retention times. For not identified compounds, only the retention times are shown.

An asterisk (*) after the retention time indicates a manually integrated peak.

An asterisk (*) after the compound name indicates a manually assigned compound.

Zooming

To zoom into a specific section of the chromatogram, you can simply drag the mouse over the required section.

To move the x- or y-axis, you can grab the axis and move the mouse. The mouse arrow turns into a double arrow when it is located over an x- or y-axis.

For more information on zooming, see Adjust graphs.

Scaling

The Chromatograms toolbar offers different options to scale the chromatogram. For more information, see Scaling Options and Display Mode.

Peak selection

At the top of each peak, the retention time and a triangular marker are shown. For the selected peak, the marker is filled with the color of the chromatogram. For identified peaks, also the compound name is shown. You can select any peak by clicking the marker or the peak area. The peak selection is synchronized with the selections in other windows (see Data Synchronization).

Export

The context menu of the graph offers the possibility to export it as a graphic. You can copy the graphic to the Clipboard or save it as a file.
