GC MS lens problem... Or voltage?

Dear all,

I'm everything but a specialist of GC MS... Today I noticed that I could not get any mass spec anymore!

I did run a quick check and... TADAM... look at the attached picture... Something is wrong with the lens 1...

How could I fix the problem? (Before that plot showed a curved line but at least now it is straight but still not passing through to origin...)

Thanks a lot for your help,

Kevin

Hi Kevin

Please give details of your system. Brand, model, etc.

Did you open the analyzer or cleaned the ion source before the problem?
