13.2.2 Setting the detector
13.2.2.1 Screen description
Press the [DET] key to display the detector main screen shown in Fig.13.2.2. Here, set
the detector temperature, the detector gas flow rate, etc.
When the detector is configured in the analytical line, the output signal settings appear
in the lower portion of the screen.
13.2.2.2 Parameter list
DETECTOR CONTROLLER
Selection: On/Off, Default: On
When a detector is set to “On”, its current and voltage are controlled.
When a detector is configured in an analytical line and set to “On” here, the detector is con-
trolled and its signal monitored. However, even if a detector is set to “Off”, the gas flow and
the detector temperature are controlled, if the detector is configured in an analytical line.
TEMP
Range: 0.0−450.0 °C, Default: 25.0 °C
Set the detector temperature. Normally, set the detector temperature approximately
30 °C higher than the final column oven temperature to prevent contamination by high
boiling point compounds.To set the maximum temperature limit, refer to “16.6.4 Setting
the maximum temperature limits” in “16.6 GC Configuration”.
FLAME
For display only
On: ignite the flame.
Off: extinguish the flame.
FILTER TIME CONSTANT
Selection: 4 ms/5 ms/10 ms/20 ms/50 ms/100 ms/200 ms/500 ms/1 s/2 s, Default: 200 ms
This constant affects the processing of the detector signal.
As the time constant increases, noise as well as the peak height are reduced. But the
peak width becomes wider.
