Hi all,
My GC-MS instrument (Agilent 7000) shows the following error at 20-40 minutes after beginning run:

"QQQ Fault Detected: 3.12 Collision Cell RF Driver Cannot Maintain the Request RF Peak Voltage"

then no data are saved. Before appearing this error, data are saved without problem.

The instrument is tuned well and every other things are seems to be OK.

Any idea?
Have you power cycled the instrument? I have had some errors on a 7000 that happen and the only way to correct them is to shut down completely and reboot. It seems that clearing the memory on the system will flush out some bad data that causes errors.

If that doesn't fix the error then it could be in the board that powers the RF for the collision cell.
The past is there to guide us into the future, not to dwell in.
