Agilent 6890GC/5973MSD
The MS automatically shut down after 18 min. Could you please help me figure out the possible reasons?
Thanks a lot.

Is the power to the MS getting turned off/is it venting?
Or, is the data not getting collected after 18 minutes?
If it is just not collecting, but the GC continues to run, you probably have a "Detector Off" time of 18 minutes under MS Parameters.
Are there any errors in the log?

wl_yang,
You have a leak and the turbo is not getting up to speed in the specified time.
Best regards.

How often has this happened ? Does it always happen at the same time during a run ?
