What are the unanswered (and unasked) questions in ion analysis?

This article "free-associates" through a few of the questions that remain unanswered and unasked in ion analysis. Some of the questions nosed into include: What limits precision and accuracy in ion chromatography and capillary electrophoresis?; What is the cause of nonlinear calibrations curves in suppressed ion chromatography?; Why do we use ion chromatography?; What is meant by speciation in ion chromatography?; What self-imposed limits are restricting our application of ion chromatography?; and What is the relationship between ion chromatography and capillary electrophoresis for ion analysis?.
