    GC/MS tuning problem


      Hi All,


      After I doing maintenance for our GC/MS (EI source), I ran the tune, it shows this problem. I have re-cleaned the EI source, checked all the cable to ensure they were in the right place, checked the column inserted into the MS to ensure it was not inserted too far into the MS.


      After doing all of that, I tuned the GC/MS again and still see the same problem with high Em voltages and tuning failed. Do you have any idea how to fix it?


      Thank you!
