hissing split vent on Agilent 7890

Discussions about GC and other "gas phase" separation techniques.

Should I ever be able to hear gas coming out of the split vent on the back of the 7890? Pressure too high?

We have a new 7890 and I haven't heard this before on our other 7890.
Hello

If you don't have massive leak there is nothing to worry about...It is normal for S/SL inlet. The bigger spit ratio you have, the bigger split vent flow you'll have (and sometimes you can even hear it)
Just be aware that you should use "gas saver" option to save carrier gas.
