Hello, we are having excessive levels for our air/water check after changing the gas cylinder on our Agilent 7890B.
H2O: 156.61
N2: 308419.93
O2: 8.38
CO2: 13.49
N2/H2O: 196939.42
I checked for leaks in the cylinder, changed the o-ring and septum, left it overnight at a high inlet temperature (300C), and tried running a 'bakeout method' with a solvent delay as long as the method. Still the values are excessively high. I'm not sure what else to try, does anyone have any suggestions on how to resolve this issue?
Thank you
