The new multidimensional chromatographic instrument SFC-GC×GC enables the temporary storage of SFC fractions inside sampling loops for subsequent analyses by GC×GC. The interface was configured for the characterization of heavy petroleum fractions. The SFC dimension was adapted to perform a group type separation into saturated, unsaturated and polar fractions. The GC×GC dimension was set in order...
A new multidimensional chromatographic instrument has been developed to perform both SFC-GC×GC and SFC×GC×GC, in response to the challenge of complex matrices characterization. The design of this online system is fully described and enriched by theoretical and practical discussions. A new interface has been investigated: this interface allows the temporary storage of SFC fractions inside sampling...
