Hi there, I've recently started using a GCMS (7890A + 5975C MSD). The tune has failed and the GC shows a flat line at 0.5 whenever a sample is run. I've attached all relevant photographs I could think of, including the GC spectra where it all stopped working and what the spectra from the previous run looked like.
Would anybody be able to assist me with this? Unfortunately I don't have anyone on site that can be of any assistance.
Thanks for your time and I'm happy to provide as much additional information as possible.
