Analysis of Metal Finishing Solutions by Ion Chromatography

摘要

Ion chromatography is very effective for ionic and polar species determinations. Separation of the analyste into pure peaks simplifies detection compared to detecting the same species in the unseparated sample matrix. One of the methods provides important improvements on existing methods, while the rest provide new and improved ways to analyze metal finishing solutions. The advantages of these methods are that considerable improvements were made in the areas of: trace ion determinations in the presence of other extremely high ionic concentrations, analysis time, analyst intervention, sensitivity, automation, and multi-ion determinations while maintaining equal precision and specificity compared to traditional chemical methods now in use.
