neither gc nor ms data collected, consult logbook

Hello,
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

  • Hello, 

    I see this has been solved, but for the sake of others seeing this error I will explain what was the cause was for us.

    After much semi-unproductive trouble-shooting with the remote cable and restarting instruments and computer, we noticed that the start of the first MRM window had accidently been moved to before the solvent delay time (solvent delay (min) = 6, start time MRM TS 1 = 3). Now we have corrected this (solvent delay (min) = 6, start time MRM TS 1 = 7), and we have not seen the error again. 

    Hope this is helpful and good luck to all!
