GC cycle time


Im currently running a headspace method where Im getting very poor reproducibility in peak area. 

I want to make sure that my GC cycle time is set to its correct value and that my vials are not spending enough or too much time on the carousel. the current cycle time is set to 46min based on the below parameters. 

1. vial equilibration is 60min

2. vial pressurization is 0.4min

3. loop equilibration is 0.2min

4. inject time is 0.5min.

5. run time is 32min, the GC must cool down from 245C to 35C which takes probably 5-6min. 

therefore would my cycle time be around 95min? 

the GC is 7890A

thank you
