Cannot get rid of water in source chamber on qtof 7250. Helium checked and is free of water. I think only helium gas flows into MS. What could be going on? right now it's at 30% water vs ion 69.
I sprayed all over with duster looking for leaks. I would expect any leaks to result in high oxygen as well as water, however, oxygen is at acceptable levels. and no leaks detected.
tuning is not acceptable. not sure if this is related to water or it is another issue. not enough resolution for ion 502.
Scheduled agilent tech to come in but who knows how soon they can come.
