While using GC Sampler 80 for headspace analysis, is there a way to delay the split flow so that the split won't be turned on during sample incubation?

Question

We have a 7890A coupled with GC Sampler 80. I noticed that when we use a split method, the split flow will be turned on in the beginning of the incubation. This is quite a waste of helium gas in my opinion. I have tried to look for any delay settings and was not able to find any. Am I missing anything? Is there any way to save helium?

Yes, you should be using the A-HS-Inj Cycle as it has the commands in it to set Prep-Run and save gas. I think it's best for you to call your local country's toll free number and have one of the online technical support engineers walk you through the necessary steps on the phone.
