Applications
Sampling with a Jar
The F-960 comes with an extra accessory sample probe for
creating a closed-loop system for sampling enclosed headspace
in a sealed container. The example below displays a glass jar
with a built-in septum for easy insertion of each sample probe.
The standard sample probe is connected to the intake/inlet of
the F-960 while the closed-loop sample probe is connected to
the outlet. By creating a closed loop, the rigid jar will not
pressurize by the displaced sample gas removed from the jar.
The gas will be drawn into the F-960, analyzed by the sensor,
and then re-circulated back into the jar through the closed-loop
sample probe. For larger jars/containers, CO2 gas may settle to
the bottom. This can be compensated by adding a small
circulation fan inside the jar or by lying the jar on its side closer
to the sample syringe.
