Why use headspace?
the headspace gas is injected, making it a ‘clean’ technique that requires
solvent-free technique, meaning reduced environmental impact.
analysis of samples that cannot be directly injected into the GC.

Automated headspace and headspace–trap
The Centri system from Markes International fully
automates both regular headspace sampling and headspace–trap, with cryogen-free
focusing. Headspace–trap results in enhanced sensitivity by larger injection
volumes and multiple extraction cycles from a single sample to be
‘concentrated’ in one GC–MS run, as well as improved peak shape and optional
sample splitting and re-collection for repeat analysis without the need to
repeat extraction steps.
