we have a 5977A MS from Agilent in our lab.
I cleaned the ion source for the first time. When I wanted to reassemble it I notived that the lens insulator has two really small cracks at the thinner part.
Now, when I try to allign the entrance lens and the ion focus lens to touch each other the insluator gets too big of a diameter and does not fit in the ion source body. However, if the lenses have a gap between each other they do fit into the body perfectly.
I do not remember or know if the lenses are supposed to touch each other or if there is supposed to be this gap and I am just paranoid.
also does someone know if the cracks in the insulator can become an issue?
Thanks a lot!
