Thanks for the reply. R/O/I is ROSE / Omegameter / Ionograph which is used as a baseline for Ion Chromatography.

Acceptance Criteria Ion Chromatography testing?

Electronics Forum | Tue May 22 19:28:31 EDT 2012 | Rick Thompson

Are there any established acceptance criteria for contaminants based on Ion Chromatography testing? I've found some references to certain levels for some contaminants but there doesn't seem to be any industry consensus. Any feedback or reference to l

edmaya33, you're correct about what J-STD-001E says, but recognize that the measure that you refer us to in not IC [Ion Chromatography]. It is modified ROSE [Resistivity of Solvent Extract] ... or whatever they call modified ROSE now-a-days
