Handling a sample
If possible, filter and dry the sample before introducing it to the Micro-GC. It is advised
to use an External Sample Filter Unit between the injector and the sampling device.
The Filter, male must be hand tightened into the Filter Female, followed by a 1/8th turn
with a 7/16" wrench. The arrow on the Filter Female should be directed towards the
Fingertight Fitting.
