I am interested in the identification of the C6,C7 and C8 isomers in natural gas. We are running an isothermic multidimentional analysis performed in a GC HP 6890 with a TCD and FID. How could I do for the identification of isomers in the gas? Which is the response factor usually used for the isomers?
What is the usual technique for this determinations?
Thank you very much.

I suggest you contact the Gas Processors Association (GPA) and ask for GPA Standard 2186. This test method includes several chromatograms of an extended natural gas analysis with the peaks identified through n-C9. 2186 also includes a table of relative response factors for the TCD and FID.
