conductivity or uv/vis ion chromatography focuses on many ionic components in our environment whether nutrients or pollutants drinking water or wastewater pharmaceutical products or contaminants in them ic permits reliable analytical statements about their ionic composition ion chromatography has the aim of first separating the ionic substances and then quantifying them reliably as we are dealing with ions detection is usually performed with a conductivity detector if matrix effects or inadequate separation of the analyte ions negatively affect conductivity detection or even render it impossible then the use of an alternative detection method can supply important knowledge should conductivity detection not produce a result then the absorption of ultraviolet or visible light by the sample may yield the correct analytical solution a prerequisite is that the substances absorb part of the light passing through them 5
