10.3 Program example
•
After starting the sample program the pump will get started and the
sample line will get flushed for two minutes (purging time) with sample
gas.
•
Simultaneously the enrichment tube will be cooled down to 30°C
(sampling temperature).
•
Next VE1 is switched and sampling starts with a flow of 21ml/min
(calculated gas flow) until a volume of 300ml (sample volume) is sucked
through the enrichment tube.
•
Now the CP method (sample or calibration) is loaded and VE1 is
switched back.
•
The enrichment tube gets heated very quickly up to 230°C (Injection
temperature).
•
Simultaneously the GC oven program is started and data acquisition
begins.
•
3 minutes (Injection time) later the enrichment tube starts to cool down
to the sampling temperature of 30°C and the system is ready for the
next start.
•
This start may occur before the GC oven temperature program was
finished.
