GCxGC separations, performed using a dual-jets CO2 modulator, were optimized using a test mixture representative of the hydrocarbons found in petrochemicals. For complex samples, a comparison of GCxGC qualitative and quantitative results with conventional gas chromatography (1D-GC) has demonstrated an improved resolution power of major importance for the processes: the group type separation has permitted the detection of aromatic compounds in the products from dehydrogenation of n-paraffins and from oligomerization, and the separation of alcohols from other hydrocarbons in Fischer-Tropsch products. %G English %2 https://ifp.hal.science/hal-01330592/document %2 https://ifp.hal.science/hal-01330592/file/Vendeuvre_htc8_text_rev.pdf %L hal-01330592 %U https://ifp.hal.science/hal-01330592 %~ ESPCI %~ IFP %~ CNRS %~ PARISTECH %~ PSL %~ ESPCI-PSL
