Hi Community, I'm unfamiliar to GCMS systems and I'm assigned to work with a 7890B GC system and 5977B MSD system. The system has been sitting unused (completely turned off) for about a year and I'm not sure what's the correct procedure to get it up and running again. So far all I have it, I'll use Auto Dat and HiVac Pressure and wait for the system to reach between 10e-5 and 10e-6. Then I'll air and water check, autotune, and tune evaluation. Any help would be greatly appreciated!! Thank you for reading!
