72 Operation and Maintenance Manual
Start-Up Procedure
1 Turn on the GC and set the carrier flow rate.
2 Turn on the hydrogen and oxygen to the Dual Plasma Controller.
3 Turn the Detector from STANDBY to ON.
4 Press the PUMP button until the red LED illuminates. Make sure the
vacuum pump is running.
5 Turn on the oxygen to the ozone generator and set the regulator inside the
front door of the Detector to between 3 and 6 psig.
6 Allow the system to evacuate for approximately 1 minute before turning on
the ozone at the front panel. A properly functioning system will show a
background signal deflection between the ozone on and ozone off.
7 Turn ON the Dual Plasma Controller using the ON/OFF switch on the rear
panel of the Controller. As the Burner heats, the SCD or NCD background
will increase and then slowly decrease. The hydrogen and oxidant flow will
automatically start when the temperature of the Burner rises above
approximately 325 °C.
8 Check the LCD display of Dual Plasma Controller to confirm that all
pressure, temperature, and signal responses are within the desired
specifications.
WARNING
The Burner is hot. Do not touch the Burner. Let the Burner cool before performing any
operations involving the Burner.
