摘要： A method of analyzing a sample solution containing an ionic species of interest paired with an ionic species of the opposite sign comprises introducing the sample solution into a separation column with an eluant solution, introducing an eluate from the separation column into the inner passage of a diffusion type deionizer of the double tubular construction which is defined by a tube of an ion exchange composition, while a scavenger solution is introduced into the outer passage of the deionizer in a direction of flow opposite to that of the eluate in the inner passage, whereby the ionic species of the opposite sign is removed from the eluate into the scavenger solution, and measuring the electric conductivity of the eluate from the deionizer to thereby determine the concentration of the ionic species of interest in the sample solution. An apparatus for carrying out this method is also disclosed.

摘要： Method and apparatus for analysis, by ion chromatography, of anions, in a sample solution, wherein accurate analysis of anions in the sample solution is obtained by passing carbonic acid, through a prescribed membrane, into the sample solution, thereby completely eliminating or sharply lessening the so-called water dip effect. The method and apparatus are further directed to enabling anions in the sample solution to be accurately analyzed by passing prescribed cations, through a prescribed membrane, into the sample solution, thereby depriving the sample solution of interfering anions otherwise abundantly present therein.
