I am analyzing terpenes on GCMS-LI 5975C 7890A.
For some reason it is not collecting mass spec info and the datasim.ms is blank. I see peaks for Retention time, and it will compare the mass spec from the data.sim, but under that window should datasm. peaks and theres nothing. Please help identify why this is happening. I have adjusting the MS SIM/Scan parameters and selected acq. mode to "Scan" which is what i use on my GCMS-HS and works great. But for some reason its not pulling data on the gcms-li. Cannot figure out what's missing.
