Hello,
I pumped down a GC-MS (7890B/5977B) overnight and I continue to get a high water reading.
My air check readings are as follow:
water: 15%
N2: 7%
O: 2%
The 7% N2 is typical for our system since the inlet is connected to the headspace unit, but I am unsure of the high H2O reading.
What's the most likely causes for high H2O, normal N2 reading?
