ICP-MS manual tuning

I could use some resources on manual tuning for ICP-MS systems.


I'm a relatively new user, and I'm disappointed at the seeming lack of useful information available through Masshunter Help, Agilent user manuals, or online. 

 

Specifically, I'm looking for resources pertaining to how lenses, plasma settings, and various other tune parameters  affect sensitivities/peak shapes.

 

What are the purpose of the various lenses?  How do they affect the ion beam and sensitivities?

The same question for gas flows and all of the other various tune parameters.

 

 

We currently use a 7900 system for drinking water applications (EPA).  The autotune alone is often not sufficient to meet tune criteria, making manual tweaking necessary.

 

Thank you.

  • Hi....I just have Mass Hunter on the 7700 and 7900 here. To fire them up toward the beginning of the day it normally inquires as to whether you need to go through the underlying startup program when you light the plasma which will heat up the instrument at that point move to the tuning arrangement and run an autotune and a tune check.

    You can avoid these and do the tune physically. You click on the Batch tab of the interface and you can get to the tune boundaries there and do it physically.
