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.
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?
When source of MS was cleaned then that time any GC maintenance performed means consumables like septa/ liner/ gold seal etc were replaced or not
Not those consumables, but consumables in the source were replaced.
