Carrier gas flow

Entering checkout method setpoints

Confirm ignition by holding a shiny object like a wrench over
the detector vent. If the flame is burning, moisture will
condense on the wrench.
The tables of checkout conditions on the following pages give
suggested pressures to achieve the required carrier flows. These
are good starting values and probably quite adequate for the
present purpose.
The GC is controlled by a set of values for temperatures, times,
signal choices, and so on, collectively called setpoints. How you
will enter setpoints depends on if you use Cerity Chemical for
instrument control and data analysis, or if you use the
instrument in standalone mode with an integrator.

Working with Cerity Chemical

If using Cerity Chemical software, install it now. It will set most
GC setpoints for you. Refer to the Operation manual on the
6820 User Information CD-ROM for information on:
• How to use the GC with Cerity Chemical
• How to set flows
• How to run analyses using Cerity Chemical
Then refer to the online information accompanying the Cerity
Chemical software to learn how to use the software to control
the instrument for a sample run.

Working with an integrator

If using the GC with an integrator, you will make settings using
the GC keyboard.
