Condition the GC System
As the Injector and column were conditioned earlier, this procedure represents
a quick conditioning of the entire GC system including the detector. Follow the
steps below to build an analytical method to condition the GC system.
•
Press the INJECTOR key and verify that the Injector temperature is
250°C. If the Injector is either a 1177 or a 1079 PTV verify that the initial
split state is ON and that there is no split time program. Set the split r atio
to 100.
•
Press the COLUMN OVEN key and set the initial column oven
temperature to 250°C.
•
Press the DETECTOR
key and set the detector oven temperature to
300°C. If the detector is an FID, wait for the detector zone to get above
100°C (check here on page 287 for more Ignite conditions) and then press
the ignite button to ignite the flame.
•
Allow the system to condition for one hour.
Build a Method to Analyze a Test Sample
The conditions for running a test sample depend on the sample chosen. The
test sample is typically one of the following:
•
The column test mixture supplied by the column manufacturer,
•
a Varian Test Sample, or
•
a test mixture you select as an indicator of system performance for a
particular analysis.
