Changing the Electron multiplier on Thermo MSQ
Posted: Tue Aug 13, 2013 1:12 pm
We had change the Electron multiplier on Thermo MSQ (Finnigan™ Surveyor® MSQ™ Plus, HPLC) and we have problems now.
We can see any masses when would we run basic function test (acetonitrile/water=50/50). We cannot see the right masses for monomer or dimer of acetonitrile.
Have someone ideas what is the problem?
