Apparatus for analysis of anions

Image Number 3 for United States Patent #4533518.

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.
