This could be due to an issue with an electronic board. We would advise you call you local support line. If the in the United States the number is 1-800-227-9770 opt 3.
Just following up with you to see if you were able to get to service to take care of your issue? Could you mark as correct if this helped you.
Sorry for the delay. Yes! We put in a service call and all is well now!
I have same problem but I have LCMS (QqQ) instead of GCMS. I don't know if I will have same solution with me too. Was problem IN or OUT of QqQ ? If it is IN, obviously need to vent but if OUT don't need to vent which makes easy to correct the error. It is happening randomly but very frequently and recently frequency increased (10-15 times in a day). I believe it is contributing the peak area; means, out of 10 replicate injections (from same vial), one or two (random) replicates will have inconsistent peak area (0.5x or 2x etc.), while rest of replicate injections are very consistent and reproducible. Again, I am not sure if this error is the reason of inconsistent area!
Other community members, any help is greatly appreciated.
Thanks in advance
