Simplify Monitoring of Ultratrace Levels of Corrosive Ions in Steam Power Systems with On-Line IC

Ion chromatography (IC) has become the major technology to determine the significant components in power plant water that contribute to corrosion. Accordingly, determinations of anion ionic (fluoride, chloride, and sulfate) and cation ionic (sodium, potassium, magnesium, and calcium) components are monitored by laboratory analysis. Laboratory determinations of such contaminants have been refined over the years to allow sub-ppb (ug/L) levels of detection. However, the on-line determination of these corrosive contaminants offers some practical benefits over lab-based analysis.
