7.3.2 Parameter list
FILE LOAD
Selection: File No. 0−9, Default: Current file
Selects a file to be loaded the next time the power is turned on or the GC restarted.
START GC
Selection: Auto Start/ Manual Start/Semi-Auto, Default: Manual Start
Sets the start method for the next time the power is turned on:
Select “Auto Start” to automatically start the GC.
Select “Manual Start” to start the GC by presssing [Start GC] (PF menu) from the [SYSTEM]
key main screen.
Select “Semi-Auto” to start carrier gas flow only. The GC must still be started by pressing
[Start GC] (PF menu) from the the [SYSTEM] key main screen.
START TIME
Range: 0.0−6000.0 min, Default: 0.0 min
Sets the period of time after gas control starts until temperature/detector control starts.
The “Start Time” value on the [SYSTEM] key main screen is set here.
The start time set here can be overridden by entering another start time in the [Start GC] (PF menu)
screen.
This function is useful if the preset start time is too long.
START TEMP/DET
Selection: Yes/No, Default: Yes
Select “Yes” to start temperature/detector control after the start time is elapses.
Select “No” to continue carrier gas flow only without starting temperature/detector control.
DETECTOR
Selection: On/Off, Default: On
Prepares the configured detector for analysis, but does not ignite the FID or FPD.
The “DETECTOR” setting on the [SYSTEM] key main screen is set here.
AUTO IGNITE
Selection: On/Off, Default: On
Establishes FID/FPD ignition conditions.
Select “On” for the FID/FPD detector to stand by in the ignited status. Select “Off” for it stand
by without igniting.
The “AUTO IGNIT” setting on the [SYSTEM] key main screen is set here.
CLEAN UP
Selection: Off/Analysis Para/Clean Up Para, Default: Off
When performing clean up, select whether to use an analysis method or the program set in
[Clean Up] (PF menu).
The “CLEAN UP” setting on the [SYSTEM] key main screen is set here.
7.3.3 Example: starting the system with carrier gas flow
In this example, carrier gas flows for a certain period of time before temperature control
begins. The length of time the carrier gas should flow depends on how long the carrier gas
flow was shut off.
• If the same column is used in the same analytical flow line as the day before:
set a START TIME of approx. 10 minutes.
• If a different column is installed on the same flow line that has been in use:
set a START TIME of approx.10 minutes.
• If the system has been out of use for a time with no column connected:
set a START TIME of 1 to several hours.
