neither gc nor ms data collected, consult logbook

I have a problem with GC-MS. When I run sample, there was no GC and MS signal collected ( neither gc nor ms data collected, consult logbook)
I tried to tune the MS, filament seems OK, and MS tunes well. Once start injection, MS loaded method, and showed running the method but no data were retrieved and no snapshot acquisition.

GC 7890A
MS 5975C

  • We have seen this on occasion even though things were configured correctly. Usually a solution to the problem is to reboot all the modules including the GC, MS and computer. To confirm that this has worked I do a fake injection by setting the injection source to manual and starting a run without injecting anything. If data is collected then it worked

    i don’t think we have ever worked out what causes the issue.
