Hi,
What is the acceptable criteria for the Air and Water leak check on a GC-MS?
For 69, 18, and 28, I have a relative abundance of 100, 1.61, and 1.15. This seems really low. Can you please give me suggestions as to what I should do?
Thank you!

Thank you, ISH. It seems that my abundances are low for 69, 219, and 502 m/z. I have 231360, 57248, and 2577, for 69, 219, and 502, respectively. Do you have any suggestions? Thank you.
Above one is in detail document of msd evaluation.
In your autotune report, can you check what is value of EM..
By the way, i shared info herewith to compare / cross check..
Thank you. I am wondering if the problem is associated with air in the column/conditioning the column. The Hi-Vac also looks to be the problem.
Please attached autotune report..
Can you see it now?

I am unable to get that autotune report due to the age of my software. We do not have a PDF software on the computer and the computer is not connected to the internet
See, water can be removed by baking of ms and conditioning of column but for air leak need to check all points mentioned in documents i shared..

Autotune print out is coming or not.
No, Autotune print won't work either. The only thing I can generate is what I uploaded earlier
