I am facing an odd problem with one of our GC-MS systems, it is an
* Agilent 7000 MSD
* GC 7890a
* GC 80 sampler (actually PAL xt?)
Between samples of a sequence, the GC is occasionally not ready and will never be ready. The status on the GC is "external device not ready". The data acquistion shows a dialog box asking me to override the GC ready. Choosing the override option seemingly leads to a normal run with normal results.
It is a bit annoying to manually override every other sample, if not even every sample.
When the error appears and one pulls the remote start plug from the MS, the autosampler starts its work, but obviously the MS does not switch on the ion source. From my understanding this means that the MS is not "ready" and stops the entire setup from being ready.
Not sure if connectd: quite a while ago an Agilent technician came and updated firmwares, which led to the MSD displaying "GC comm. disabled" (or similiar, I need to double check that). Apparently, I was told, this is not necessarily true.
Does anybody have a hot tip what to do with that info?
Best
