Unknown peaks Custom Calculation

Question asked by camelia on Dec 4, 2018

Greetings!

I am using OL 2.3 and want to calculate the concentration of unknown peaks against the response of the "Dimer" compound which is present in the sample chromatogram.

I have used the following:

Peak_Area/CurrentInjection.SignalByName("DAD1I").PeakOrGroupByName("Dimer").Compound_ResponseFactor

 

and the unknown peaks present in the chromatogram are being correctly quantified against the response of the Dimer which is what I need. However, I need to refine the calculation so that it only does the calculation for unknown/not identified peaks as I do not want the calculation for all peaks in the chromatogram. How can I make the calculation specific to unknown peaks please?

I am also wondering if when I use an instrument from a different vendor if the signal name will be the same. I will be using the same acquisition method so does this mean the signal name will be constant across different vendor instruments?

Thanks
