13.1.5.1 Confirmation prior to FID ignition
Confirm the following points prior to FID ignition.
1. Connect the column.
2. Specify the FID to be ignited in a flow line. (Refer to “8.3 Specifying the Analytical
Flow Line Components ([Line Config])”)
3. Set the FID to be ignited to On. (Refer to “13.1.2 Setting the Detector.”)
4. Turn the main valve of the gas cylinder to supply gas.
5. Set the flow rate of the detector gas. For APC, press [On/Off] (PF menu) on the
screen to set the detector gas so that all gas control is turned on.
(Refer to “13.1.3 Setting the Detector Gas (manual flow controller)” or “13.1.4
Setting the detector gas flows(APC)”.)
13.1.5.2 FID ignition procedures
Q Automatic ignition
