I have a problem with one of my MSD5977A of AGILENT.
At the beginning I had decreasing in general sensitivity and was decreasing week after week until I cannot use it anymore. I Vented the MSD and cleaned all the source (Like I always do with my other MSD : Alumina powder and subsequent sonicing bath with solvents) but the sensitivity was still bad.
I decided to run a Ramp lenses and the emission ramp was curious. I had never seen that before, The emission show one pic for 69 and then goes crazy for 219 and 502 sometimes it got a topped line, after that no emission showed and sometimes it goes up and down. I contacted AGILENT and they told me to replace the source. It's expansive and I managed to change almost all of it, except the repeller assembly (the heater block only) and the body.
Still have the same issue. I want to know before ordering the remaining parts if that could be an electronic problem?
And do I focus too much on that, since the new repeller still topped.
Thank you for your help,
