Agilent 7200 QTOF Collision Cell N2 Flow - Not Running MS/MS

Hi, I'm running an Agilent 7200 QTOF with a 7890B GC. Since installation there has been a 1.5 ml/min N2 flow into the collision cell, even though we are not running in MS/MS.

Just wondering is this typical? As the instrument can run at a much higher vacuum with the flow off/waste less N2.

Thanks in advance!
