For an SCD or NCD, gas types are usually set once. The SCD
uses oxygen for the ozone supply gas and air for the oxidizer
gas, while the NCD uses oxygen for both.
To configure the gas types for an SCD or NCD by using the GC
keyboard:
1
At the GC keyboard, press the keys to access the detector, for
example [Config][Front Det].
Scroll to Oxidizer Gas and press [Mode/Type].
2
Scroll to the correct gas type, Air (SCD) or Oxygen (NCD), and
3
press [Enter].
If using data system control, you can set the gas types through
the data system.
1
From the data system, open the GC parameters user
interface. For example, in Agilent OpenLAB select Home >
Method > Instrument Setup > Configuration > Modules.
2
Select the gas types for the method.
