I just startet to work with the Thermodesortption/GC-MS-System. I use the Markes Thermodesorber (Ultra Series2 + Unity Series2) coupled with a GC/MS.
I get more and more used working with the system and reading a lot in the Application Notes. But there are still some things I didn’t find out yet.
Where can I set the Flows at the Unity-Software (Column Flow, Desorb Flow, Split). Today I found out, that the box which says “Enter Flows” is just for calculation, not for actually setting the Flow.
I still have a lot of artefacts in the chromatograms. Even after heating the Trap and conditioning the tubes with high temperature.
Do you know about a TD-GC-MS method in a publication? I would like to check the system to see if I can measure as sensitive as I should.
Thanks for the Help,
Best regards
