When I run tune evaluation it reports that mass 70 to mass 69 is high, as well as the mass 69 precursor, should I be overly concerned? If so how do I fix it? I'm also questioning the background/stability and I'm wondering if there is a leak or leaks. I attached the auto tune, tune evaluation and air/water check reports. When I compare recent injections of the a standard to the same injections of this standard from around 6-7 months ago the TIC baseline noise seems worse and the quality of peaks is not as good; the peaks are much smaller and not as well defined. Is this possibly due to bad background because of a leak or something else?
