490 Micro GC User Manual
If you are installing the 490 Micro GC for the first time, follow
the steps as described below.
If you are performing a re-installation, see
Recovery Procedure"
Carrier gas cylinders should have a two-stage pressure regulator to
adjust the carrier gas pressure to 550 kPa ± 10% (80 psi ± 10%). Set
cylinder regulator pressure to match the gas inlet pressure.
The Micro GC supports the use of helium, nitrogen, argon and
hydrogen. The recommended purity for carrier gas is 99.995%
minimum. Connect the carrier gas to the Micro GC Carrier 1
fitting (and Carrier 2 fitting, if available) and turn on the gas
flow. See "Carrier Gas Connection"
Install the external filter unit as described in
external filter unit" on page 23.
For an unheated GC channel: Connect the sample to the Micro
GC using the sample-in connector situated at the front of the
instrument (see "Front View"
For a heated GC channel: Connect the sample to the heated
sample as described in
page 25.
Connect the power connector to the Micro GC, and then plug
the power cord into an appropriate power source. See
"Power" on page 26. Be sure the power supply is placed in such
a way that the mains appliance inlet or adapter is easy to reach
for the operator, as it functions as a power disconnect switch.
