3000 Micro GC Operating Manual
3.4 3000 Micro GC Chassis Components
3000 Micro GC modules are installed into the 3000 Micro GC chassis. The
components that are integrated into the chassis are:
 Inlet Tubing, see section 3.4.1 on page 3-14
 C-Board, see section 3.4.2 on page 3-15
 OBC Board, see section 3.4.3 on page 3-15
 Sample Pump, see section 3.4.4 on page 3-16
 Carrier Gas Weldment, see section 3.4.5 on page 3-17
 Carrier Gas Inlet, see section 3.4.6 on page 3-18
 Vents, see section 3.4.7 on page 3-19
 Remote Control Module, see section 3.4.8 on page 3-20
3.4.1 Inlet Tubing
The inlet tubing is enclosed in a heated compartment which contains a short piece
of 1/16 in. OD tubing. One side of the tubing is connected to the sample fitting on
the front panel. The other side of the tubing connects to one or more modules.
Depending on instrument configuration, the tubing is split to each module.
Temperatures can be set from 45-140
° C. Typical setpoints are between 80-100 ° C.
The inlet temperature can also be turned off. The internal surface of the tubing is
deactivated to ensure the surfaces of the tubing are inert.
