Detector Signal Parameters
Flame Ionization Detector (FID)
167
OPERATING SEQUENCE
Programming a FID
Materials required:
•
bubble flow or electronic flow meter
•
detector base body/flow meter adapter
Before you begin this sequence, do the following:
•
Verify that all detector gases are connected, a column is correctly installed,
and the system is free of leaks.
•
Check the oven temperature and injector temperature.
•
Check the carrier gas flow depending on the capillary or packed column in
use.
WARNING! Hydrogen is a potentially dangerous gas. Refer to Using Hydrogen for safety
information.
1. In Main Menu move the cursor until
Detector
is selected. Press
ENTER
to
display the
DETECTOR
menu.
2. Set the detector base body temperature. This must be greater than 150 °C to
allow the flame ignition.
3. Turn
Hydrogen
flow,
Air
flow and
Make-up
gas flow
On.
4. When the detector base body is at the set temperature, scroll to
Flame
and
set it On. This turns on the air and hydrogen flows and initiates the ignition
sequence. The signal increases after the ignition. A sudden baseline deflection
also indicates that the flame is lit inside the detector. After a few seconds the
baseline should stabilize to the standing current level of the system.
5. If desired, in Main Menu move the cursor
until
Signal
is selected. Press
ENTER
to open the
SIGNAL
menu and verify the output signal.
