The function of a gas chromatography (GC) system is to provide
the most adequate conditions required for the separation of
sample components in minimal time. Conventional GC methods
use capillary columns typically 30 m long with a 0.25 mm internal
diameter (I.D.). These well-established methods produce effective
results but present a substantial limitation: the cost in time. In
fact, satisfactory separations of complex samples may take an
hour or more. The implementation of faster GC methods is,
therefore, particularly important for laboratories with a high daily
sample throughput and/or where there is a need for quick and
correct results.
