Copying a Channel

Chromeleon allows you to copy a channel to evaluate the same raw data in different ways; for example, to determine both the ingredients and the contaminants of a pharmaceutical product in one chromatogram. To do so, evaluate the original channel with one QNT Method, and then evaluate the copied channel with a different QNT Method.

 Tip: 

You may also define copying of channels in the Post-Acquisition Steps view of the PGM Editor (see Control  The PGM Editor). The sample GUID from the raw data file is copied automatically. For instructions, see below.

How To

  1. Display the sample's chromatogram by double-clicking its name in the Browser.

 Tip: 

Open the PGM File in which you want to specify that a channel is copied and select the Post-acquisition steps view, instead.

  1. Select Copy Channel on the context menu. The Copy Channel dialog box appears.

 Tip: 

To open the Copy Channel dialog box from the PGM Editor: Select Insert line on the context menu; when the New post-acquisition step dialog box appears, select Copy Channel.

  1. In the New Channel box, enter a name for the new channel. The suggested name is the name of the current channel plus _COPY.

  2. To copy the channel for all samples in the sequence or Query, select the Apply to all samples in the current sequence or query check box.

 Tip: 

This option is not provided in the Copy Channel dialog box in the PGM Editor.

  1. Click OK to start the procedure.
