section
Column
Sets inner diameter, length and film thickness of capillary column.
Values set here are used in column inlet pressure caluculations from
column flow rate or linear velocity (or vice versa).
If these parameters are not set correctly, calculations are not performed
correctly.
12.5.3
Gas Saver The gas saver saves carrier gas by reducing the split flow rate. 12.5.4
On/Off
Set the flow controller to be used to “On.” When the GC starts, the AFC in
the current analytical line which is set to be “On” is controlled.
――
Press Prog Sets the column inlet pressure program. 12.5.5
Flow Prog Sets the total flow rate program. 12.5.6
Split Prog Sets the split ratio program. 12.5.7
Purge Sets the septum purge flow rate. 12.5.8
Advanced
High Pressure Injection:
Sets high pressure injection, where the column inlet pressure is kept at a
high value for a certain period of time during injection.
Splitter Fix:
Keeps the split flow rate constant.
12.5.9
Offset
Performs offset calibration of the AFC sensor.
This calibration contributes to good reproducibility of results.
3.6
Next Flow
Toggles among the AFC set up screens if two or more AFCs are installed
in this system.
The [FLOW] key can also be used to switch screens.
