Peak Area Ratio of Two Peaks in Current Injection

I am working on a related substance method, and I am trying to calculate the peak area ratio between two peaks (one being the main peak) in one injection. I am using OpenLAB CDS Version 2.3.


The OpenLab CDS Help & Learning manual has guidance for area ratio between two peaks in two signals: Peak_Area/MatchingPeak(MatchOption.ClosestRT,0.1, CurrentInjection.SignalByName("DAD1A")).Peak_Area


1) Some of these syntax codes are not listed to choose from.

2) I've tried to modify the formula to fit my purpose, but doesn't seem to work appropriately.


Best regards,
