Abstract
<p>Ion chromatography (IC) has been widely used with conductivity detection. Conductivity detection is semi-selective to the ionic solutes. The response of conductivity detection depends on limiting equivalent ionic conductances, which are different for various kinds of ions. Most of the analytical instruments, including IC, required a calibration procedure with an analyte standard. The accuracy of the results depends on the quality, stability and purity of the standard. The universal detection, which is the way to quantify without an analyte standard, is an ideal way on the chemical analysis because it can achieve the quantification of unavailable compounds and decrease the labor for preparing the standard especially for multiple quantifications on chromatography. In IC, many kinds of method for universal detection have been reported. Most of these are based on ion exchange. Ions are the chemical form which has a electrical charge. Ions can be exchanged to the other kinds of ions while keeping charge balances. This phenomena is important in universal detection with an indirect photometry, and replacement IC. Furthermore, direct universal detection has been achieved by the detection of charged aerosol, ionic charge, and carbon amounts on organic compounds. In the present review, these universal detection methods are introduced.</p>
