GC-DSQ II
Posted: Thu Mar 20, 2014 10:44 pm
Dear all,
All the items of the auto tune of our GC-MS DSQ II are passed, but we noticed that the intensity is low for example:
Peak 69.0 intensity 1651305
peak 131 intensity 491600
Furthermore, the peak of 502 appeared as a split peak and too noisy.
Have you any idea about the cause of this problem and its solution?
Please note that:
1- The background scan spectrum from 10 to 650 is ok.
2- The air/water spectrum from 10 to 90 is ok.
4- All the diagnostics are ok.
5- The DC/RF value is 0.963
6- The detector gain value is 3e5
Thank you in advance
