ResumoSpecies determined by ion chromatography are nearly all ionic, so that conducitivity detection has become the workhorse detector. However, there are several other important types of detectors which offer major advantages for determining many species by ion chromatography. These include other forms of electrochemical detection, specifically d.c. and pulsed amperometry, as well as optical methods of absorbance and flourescence. Using these forms of detection, nearly all forms of ionic species can be detected, ranging from inorganic ions to carbohydrates and peptides. In this paper, the factors to be considered when selecting a detection method are reviewed, for example, the properties of different classes of ions which make them amenable to a specific form of detection.
