IC Eluent baseline shift

[Krismo]

Hi!
We are using Dionex ICS-2000 with MSA eluent generator for cation analysis. We had some issues with babbles from eluent filter, which we fixed. Unfortunately separation is not good anymore and we ordered new columns, we try to work with those conditions until. We use gradient program and now with those conditions we have much higher baseline shift after eluent concentration change from 2 to 7 mM than we had before, could anyone suggest what it could be related? Column or something else?

Best wishes
Krismo

This is a discussion for GC problems/issues. IC issues should go in the LC forum.

Dear rb6banjo

This has nothing to do with GC but with IC. And this is the real place for IC discussion.

Sorry that I can't give a certain suggestion, but you may go to the LC forum for an answer.

Krismo, is your suppressor working properly?
