I am running method AK101 and I have an area sum setup to include everything from hexane to decane. We are using two surrogates, trifluorotoluene and bromofluorobenzene. Is there a way to tangent skim the surrogates to include their area separately in the chemstation report while still including the remaining area as the Gasoline range organics for AK101? Currently we have to manually tangent skim the surrogates and have a peer reviewer initial the chromatogram before it is considered valid.
