Hi all
I recently posted a question about reagent-free IC,
and didn't get any responses. I figure maybe nobody wants to get into a marketing brawl. If that's the case, and you have something to say about a reagent-free IC system from Dionex, please email me directly (jholt@uiuc.edu). Sorry about stepping on toes if that's what happened.
I really would like to hear some opinions about it
though, because I'm looking to get an IC and it looks like nice technology but I don't know many IC users.
peace
Jonathan

Ragent Free IC is not actually reagent free. You still have to buy a stock solution (few hundred dollars). From my experience we never used full bottle because of some leakage problems. "Reagent free" Ic means that you are not preparing solution, somebody else making stock solution and you just deluting it. This is my opinion and I might be wrong.

I am using "reagent free" IC with out any problems, at least you do not have to prepare any solutions.

There seems to be a misunderstanding in the comments made by Anonymous, (December 20). The comments seem to refer to a technology that is one or two generations older than RFIC.
With an RFIC system there is no need for any dilution steps. The stock solution comes in the form of a cartridge and the eluent is electrolytically generated from the stock solution straight into the eluent stream. For the suppression step there is no stock solution whatsoever. The eluent is electrolytically neutralized by stripping the eluent ions straight out of the eluent stream into the waste stream.
More information on RFIC is available from the Dionex website.
