Operation
1 After all the connections are made, allow 15 minutes stabilization of the temperature.
2 Connect the sample bomb to the Micro Gasifier. In case of a LPG, ensure that the liquid phase
is flowing towards the Micro Gasifier.
3 Open the sample bomb, and check for leaks.
4 Open the VENT needle valve, and allow to flush for one minute, then check the sample vent
flow at the VENT-OUTLET.
5 Open the SAMPLE needle valve, and adjust a flow though the Micro GC of 10 mL/min.
6 Close the VENT needle valve to a flow of 10 mL/min minimum.
7 Start the Micro GC run or sequence.
Monitoring the various flows by means of a soap bubble meter, or equivalent, will help setting the
optimal conditions.
In case of a high-pressure gas, the same procedure applies.
