  • My tune reports on my GC 6890N/5973 MSD have been really noisy/low sensitivity. My source is clean and I don't know what else it could be. Leak maybe?

    I made the mistake of doing a standard tune multiple times instead of an auto-tune and I know this lowers the sensitivity according to the hardware manual. Could this be the source? If so, how can I fix it?

  • For the 6400 Series Triple Quadrupole (specifically 6495B), does the checktune inject a fixed volume of calibrant solution every checktune? 

    And if not, are the intensity values of each mass averaged over a time window?
