PROBLEM TO BE SOLVED: To provide a method and means for performing accurate quantification by neither reducing measuring throughput nor adding a multicomponent standard compound. SOLUTION: In this analyzer having means for ionizing a mixture, which is obtained by adding a specific compound to a measuring sample, to mass-analyze the formed ions and quantifying the concentration of the measuring target compound contained in the measuring sample, a database which stores the signal intensity dependence to the concentration of a certain matrix component with respect to the measuring target compound and the added compound is provided and the concentration of the measuring target compound is corrected from the signal originating from the measuring target compound obtained by the mass analyzing means and the signal originating from the added compound. A multicomponent analyzer using mass analysis of low cost and high throughput as compared with a conventional technique can be realized. COPYRIGHT: (C)2009,JPO&INPIT
