The column performance is computed as the ratio of RF (Area/Amount) of two compounds that are internal standards (Di-C38 and Tri-C57).
Scope: Signal
Type: Double
Use the ByName function on the signal to find DI-C38, Tri-C57 etc.
Search Area and Amount fields on Peak or group.

Create intermediate CCs: ADiC38 = CurrentSignal.PeakOrGroupByName("Di-C38").Compound_Area MDiC38 = CurrentSignal.PeakOrGroupByName("Di-C38").Compound_Amount ATriC57 = CurrentSignal.PeakOrGroupByName("Tri-C57").Compound_Area MTriC57 = CurrentSignal.PeakOrGroupByName("Tri-C57").Compound_Amount |
Create Formula for RRF: RRF = (ADiC38/MDiC38)/(ATriC57/MTriC57) |
Compound names must be identical in the Data Analysis processing method and in the Custom Calculation formulas. |
