Is it a 5973C MSD? There's a quirk with the one I got 3 years ago. It happens every 90 or 100 days. The run starts normally and ends at the specified time, but there's an error message at the bottom:
"Neither GC nor MS data collected. Consult logbook." But the log book has no additional info.
The fix is to turn off and turn back on the Power button on the front of the MS.
Then it will happen again in 90 or 100 days...just repeat the process.
(I used to be concerned about turning off the MS, thinking the turbo pump should be allowed to wind down and come to a complete stop before re-starting. After many years, and surviving dozens of brief power outages during storms, now I just push the power button twice, less than a second apart. Has anyone reached the same conclusion about turning off and on the MS?)

Hi, I have a problem with GC-MS. When I run sample, there was no GC and MS signal collected.
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 simply no TIC. Column no problem. when I tried to see the snapshot, no response.Thanks!
