摘要： A method and apparatus for determining, by use of ion chromatography, a microconstituent contained in a major constituent as impurities present in the major constituent. The invention causes only that portion of the effluent from the detector, shown on an ion chromatograph, that corresponds to the neighborhood of the microconstituent to be led again to the collecting valve. Thus, the microconstituent of the solution can be determined quickly and easily, without reference to the kind of microconstituent being tested.

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.
