The Headspace Autosampler is designed to meet
the requirements of static headspace injection for
GC analysis. The swivel head design simulates the
movementsofmanual direct injectionandeliminates
the need for transfer lines.
The injection tower smoothly transports vials to
the 6 position incubator, where they are orbitally
agitated at the user-programmed temperature.
The heated syringe then samples the headspace
and injects directly into the GC. The 2.5 or 5mL
syringe is purged with inert gas after injection.
The incubator oven and the heated syringe have
the same programmable temperature range of
40° to 150°C. The rotating design leaves the
injection port available for manual injections at
any time. Theautosampler processessamplesso
that headspace injections start immediately after
previous run is completed.
