I performed an S tune to check if it was working properly and during the tune, I noticed at multiple times, it flashed "No emission current" and then the mass spec would turn back on. The tune did complete and looked pretty good.
I ran a blank on a nine minute method and everything looked good. I then ran a blank on a general screen which lasts 19.83 minutes and at multiple times, there was an error saying the mass spec had turned off, creating inverse peaks on my chromatogram.
Has anyone had this problem where their filaments seem to flicker on and off? I checked the connections to the filaments and everything seems to be connected properly. This MS also had its ceramic sideboard recently replaced due to a connection falling off, so everything should (theoretically) be good on that end. Is there any possible fixes to this problem?
