Analyzing 3D Amperometry Data
Extracting a Chromatogram from 3D Amperometry Data

You can extract a chromatogram from 3D_Amp data displayed in the 3D amperometry window.

1. In the 3D amperometry window, select Extract>Chromatogram to file from the View or context menu (right-click to open the context menu).

   A dialog box opens with settings for the chromatogram currently displayed in the 3D amperometry window.

2. Enter a Channel name in which to save the chromatogram, or retain the default name if you wish to overwrite the existing channel data.

3. Click OK to accept these settings and extract the current chromatogram to a separate channel. The chromatogram opens in the integration window.

You can also change the following settings before extracting the chromatogram:

• Autozero: When Autozero is enabled, the extracted 3D channel data is adjusted by the signal offset. When disabled, the total 3D channel signal is extracted.

• Extract Raw Data: The chromatogram is generated by extracting one data point per waveform from the selected Waveform Period time slice. Enter the time at which to extract the data.

• Extract Integrated Data: The chromatogram is generated by calculating one data point per waveform from the selected integration interval(s). Edit the beginning and ending integration times for existing integration intervals, add integration intervals, or delete intervals. See Editing Integration Intervals for additional information.

• Extract from all samples of current sequence or query: A chromatogram is extracted for all of the samples in the sequence or in a list of samples created with a query. Each chromatogram is named with the channel name entered in the Channel name field. After you click OK, Chromeleon extracts all of the chromatograms and then opens the chromatogram of the selected sample. To view an extracted chromatogram for a different sample, right-click the sample in the Browser, select Open from the context menu and select the channel name from the list.
