13.1.4.2 Parameter list
H
2
Range: 0.0−200.0 ml/min, Default: 40.0 ml/min(optimal flow rate)
MAKE UP
Range: 0.0−100.0 ml/min, Default: 30.0 ml/min(optimal flow rate)
Makeup gas is inert gas to be supplied to the detector to optimize its sensitivity during
capillary analysis. Nitrogen and helium can be used for the FID. Using nitrogen is
recommended because it offers higher sensitivity. Set the value to zero for packed
analysis.
GAS TYPE
Selection: N
2/He/Ar, Default: He
Set the type of gas used as the makeup gas.
Do not use hydrogen for make up gas.
Air
Range: 0.0−1000.0 ml/min, Default: 400.0 ml/min(optimal flow rate)

section
Next Flow
Switches screens to set detector gas for the left (L) and right (R) side
detectors during the dual mode of the dual FID with APC.
12.4
On/Off
Select “Off” to stop gas flow.
Select “On” to restart the gas flow.
Default value is “On”.
――
Offset
Performs offset calibration of APC sensor.
This calibration improves the reproducibility of results.
