description Integrated analysis process and device for characterization of hydrocarbons in a petroleum product, in distillation fractions, by simulated distillation. The hydrocarbons of a petroleum sample are characterized without fractional distillation by coupling gas chromatography (GC) with liquid chromatography (LC) techniques. GC simulated distillation (SD) is carried out. The separation column is preceded by a precolumn of the same nature but shorter. At the outlet of the main column, retention means (CT, AC) allow to collect and to store one or more light fractions that are sent each to a GC analytical column (6) allowing detailed analysis of the hydrocarbons, and one or more middle fractions. The remaining heavy fraction is collected at the precolumn outlet. The middle and heavy fractions are characterized by a combined LC-GC chromatography unit. Several interfaces allowing GC-GC-LC-GC coupling are described. The process and device can be applied for characterization of reservoir fluids or of refining process effluents for example.
