Connecting a Sample to the 990 Micro GC
The following sections describe how to connect your sample to the 990 Micro GC depending on
the sample inlet configuration.
The metal surfaces of the sample inlet heater can be very hot. Before connecting a sample, allow
the sample inlet heater to cool down to ambient temperature.
Front inlet
Connect the tubing for sample to the sample inlet at the front of the Micro GC using 1/16-inch
Swagelok nuts.
Connecting sample inlet accessories
Connecting the micro-gasifier
Install the micro-gasifier, and connect the micro-gasifier sample line to the internal sample inlet
using a 1/16-inch Swagelok fitting. Please refer to the Micro GC Micro Gasifier User Manual (p/n
G3535-90000).
Connect the Genie Filter to the Micro GC
Please refer to the Genie Filter Installation Guide (p/n G3588-90019).
Ensure separated liquids are properly drained through the bypass tubing outside of the Micro
GC. To operate properly, the bypass must remain free of blockage.
