Help with sulfur analysis on ICS500?

[a4analyst]

I have an ICS 500 from Dionex that I would use for sulfur species analysis. Can you recommend the appropriate column and eluent set up to capture HS-, SO3, SO4?

Thank you

Because of the "suppressed conductivity" detector technology used in Dionex IC systems, you are generally limited to Dionex columns. I would check their web site or your local Dionex rep for a recommendation. That said, I'm not sure that you can do sulfide in the same run with sulfite and sulfate, since sulfide is a much weaker acid.

Thanx Tom, this is good to know. I will wait for your further information, so I can see where I'm standing and what to do next.

You misunderstood. I meant that *you* should check the website and contact tech support.
