Range: 0.0−100.0 ml/min, Default: 40.0 ml/min
MAKE UP
Range: 0.0−100.0 ml/min, Default: 30.0 ml/min
Make up gas is supplied to the detector to optimize its sensitivity. For the FID, both
nitrogen and helium can be used. Nitrogen offers higher absolute sensitivity and higher
baseline noise than helium.
GAS TYPE
Selection: N
Set the type of gas used as the makeup gas.
Do not use hydrogen for make up gas. Do not select Ar for FID make up gas.
Air
Range: 0.0−1000.0 ml/min, Default: 400.0 ml/min
OPTIMAL FLOW (Refer to
Normally, set the flow rate of the makeup gas, hydrogen and air as follows to maximize
the FID sensitivity.
Makeup gas

controlled by a program.
Select "Off" to stop gas flow.
On/Off Select "On" to restart the gas flow.
Default value is "On".
Performs offset calibration of APC sensor.
Offset
This calibration improves the reproducibility of results.
