Analyzing 3D Amperometry Data
Viewing Chromatograms in the 3D Amperometry Window

The upper right pane of the 3D amperometry window displays a chromatogram of the selected 3D data. In integration view, the chromatogram is generated by adding responses measured throughout the integration interval to produce one integrated data point per waveform cycle. In raw data view, the chromatogram is generated by extracting one data point per waveform from the selected waveform period time slice.

 Tip:  

If the chromatogram pane is not displayed, enable the Show Chromatogram option on the context menu or click the following icon on the Method toolbar .

To select a different chromatogram:

The following methods can be used to select data and generate a different chromatogram:

• In integration view, drag the upper integration interval line cursor on the 3D or I-t plot to move the integration interval. Drag the lower integration interval line cursor to increase or decrease the interval.

 Tip:  

If multiple integration intervals are defined, you must first drag the vertical retention time line cursor into the interval that you want to adjust and then move the integration interval line cursor.

• In raw data view, drag the single horizontal waveform time line cursor to select a different waveform period time from which to generate the chromatogram.

• In integration view, add or delete integration intervals.

• Enable or disable the Autozero.
