48 Operation Manual
To Start Up the GC
Successful operation begins with a properly installed and maintained GC. The utility
requirements for gases, power supply, venting of hazardous chemicals, and required
operational clearances around the GC are detailed in the Agilent 8890 Gas Chromatograph Site
Preparation Guide.
1 Check gas source pressures. For required pressures, see the Agilent 8890 Gas
Chromatograph Site Preparation Guide.
2 Turn on the carrier and detector gases at their sources and open the local shutoff valves.
3 Turn on the cryo coolant at its source, if used.
4 Turn on the GC power. Wait for Power on successful to display on the touchscreen.
5 Install the column.
6 Check that the column fittings are leak free.
7 Set a method for the GC to use.
If using a data system, download the method to the GC.
If using the touchscreen, see “Editing the Active Method”
8 Wait for the detector(s) to stabilize before acquiring data. The time required for the
detector to reach a stable condition depends on whether the detector was turned off or its
temperature was reduced while the detector remained powered.
