The quant. aspects of online supercrit. fluid extn.-capillary gas chromatog. (SFE-GC) with a split/splitless injector as interface were studied. Special attention was paid to the discrimination behavior and the reproducibility of the split/splitless interface. A simple exptl. set-up is proposed that allows accurate quantitation in online SFE-split GC. The results obtained in online SFE-GC compare favorably with those from conventional GC with split injection. Discrimination is absent when working at sufficiently high interface temps. Finally, the effects of the CO2 flow rate, interface temp. and split ratio on both discrimination and reproducibility were studied
