Combination of Channels

Chromeleon allows you to combine two 2D channels using arithmetic operations. Each data point is created by combining the associated two data points from the existing channels (i.e., the data points at the corresponding time), using the selected operation. The resulting channel is a 2D channel, too.

 Note:

If there is a data point for channel A at a specific time but not for channel B, the missing data point is calculated by linear interpolation. That is why the resulting chromatogram may be shorter than the two original chromatograms.

You can combine channels:

• In the chromatogram: Chromeleon calculates the resulting channel immediately.

• As Post-Acquisition-Step in the PGM Editor: Chromeleon calculates the resulting channel immediately after data acquisition is complete.

Arithmetic combinations are not restricted to chromatograms in the strict sense. You can use them for all 2D channels, except for temporary channels.
