How the 7697A Headspace Sampler Works
How the HS Equilibrates a Vial
18
The 7697A HS with tray has a vial oven that can equilibrate
up to 12 vials (depending on model) at temperatures from
ambient + 5 °C up to 300 °C. In addition, the oven can
shake the vials at 9 different acceleration levels. As long as
sequence vials share the same equilibration settings, the HS
determines when consecutive samples can be loaded into the
oven to increase throughput, then automatically loads them.
The HS optimizes for throughput regardless of extraction
mode, loop fill mode, and so forth.
The 12 vial model oven can equilibrate a single vial at
temperatures from 35 °C up to 210 °C. Shaking is not
available.
