MSD stops data aquistion
My GC-MS instrument (Agilent 7000) shows the following error at 20-30 minutes after beginning run:
"QQQ Fault Detected: 3.12 Collision Cell RF Driver Cannot Maintain the Request RF Peak Voltage"
and filament is turned off.
The instrument is tuned well and every other things are seems to be OK.
The instrument was rebooted several times but the problem is still there.
After several rebooting, the MSD now gets data until 30-32 min!!! (It was already shut down in less than 30 minutes).
Is it maybe related to MSD firmware or collision cell control board?
