Two different injectors, a split/splitless injector and a programmed t
emperature vaporizer (PTV) injector were investigated as the interface
in on-line supercritical fluid extraction (SFE)-capillary gas chromat
ography (cGC). The parameters affecting the chromatographic peak shape
s as well as the quantitative performance of the interfaces in on-line
SFE-cGC were identified and studied. Particular attention was paid to
the case where modified extraction fluids were used. Experiments were
performed on two different samples. The first sample consisted of PAH
s spiked on sand at different concentration levels. The other sample w
as a polymeric material.
