| Zusammenfassung: | An integrated analysis process for characterizing a hydrocarbon sample in distillation fractions, characterized in that it comprises : - carrying out simulated distillation by gas chromatography in a layout of two interconnected columns, so as to separate the sample into at least a first light fraction and at least another, heavier fraction, collecting said fractions after separation on retention means, analysing in detail each light fraction on the one hand and each heavier fraction on the other hand by connecting up the corresponding retention means respectively with at least one gas chromatography unit and with a combined liquid and gas chromatography unit. |
