I tried to copy EIC Signal description items near each other and I don't know how to avoid this problem showed below.
As you can see, the three chromatogram is the same compound. How can I avoid this repetition?
thank you for your help.

Ok I will try it this afternoon and let you know. But I need to know why I can have acces to the field that Marty have shown. It's not normal and makes thing here more complicated. I may call my Canada Agilent representative.
Probably just something that they either added recently or something that they noticed wasn't accessible that they later fixed. Not much you can do about it unless you can upgrade.
we can have access to updates with our subscribenet account. But I need to know wich update is related to that specific field.
Hello,
The compound multiplier field in IR was added in CDS 2.7 to allow reporting of that value from the method per compound. You can back calculate that multiplier value from the compound amount and compound concentration but will need to take into account any other sample dilution factors, sample multipliers, and sample amounts used in the concentration calculation. Below is a custom calculation that will back calculate the compound multiplier for %mass calibrations where the dilution factors are used as multipliers. You really need 4 calculations to cover all calibration and dilution factor types. You should not enter 0 for the sample amount when using %mass calibrations as your concentration values will not be calculated.

Compound_Concentration/Compound_Amount/CurrentSample.Multiplier(1)/CurrentSample.Multiplier(2)/CurrentSample.Multiplier(3)/CurrentSample.Multiplier(4)/CurrentSample.Multiplier(5)/CurrentSample.DilutionFactor(1)/CurrentSample.DilutionFactor(2)/CurrentSample.DilutionFactor(3)/CurrentSample.DilutionFactor(4)/CurrentSample.DilutionFactor(5)/100*Sample_Amount
Hello,
If you CDS 2.7 the compound_mulitplier is present as an IR field. This screenshot below is from CDS 2.7 it shows the field in IR and CC.

Hello,
One option would be to stop using mass% and simply do the compound_cocentration/sample_amount calculation in IR or custom calculator.
