PROBLEM TO BE SOLVED: To provide a method for measurement of at least one element selected from plutonium Pu(IV), plutonium Pu(VI), uranium, and nitrate. ;SOLUTION: In a method for measurement of at least one element selected from plutonium Pu(IV), plutonium Pu(VI), uranium, and nitrate existing in a solution by liquid-phase chromatography, a sample, which is solution, is injected to a solid phase containing non-polar type carrier. Then, to obtain an effluent, the sample is eluted by a liquid phase having fluidity and consisting of a solvent mixture containing ammonium type counter ion, sulfate ion, an acid with 0.001N or higher normality, and an alcohol of 1-4 carbon atoms, an organic solvent which is not an alcohol, has miscible with water, and changes the polarity, and water. After that, the element existing in the solution to be analyzed is determined and the effluent is determined to determine the element or these elements.;COPYRIGHT: (C)1998,JPO
