PURPOSE:To rapidly and accurately analyze decomposed products by separating a specimen containing the decomposed products of tributyl phosphate into components by a separating column, decomposing the components to phosphoric acid ions thereafter and coloring the phosphoric acid ions. CONSTITUTION:A career solution is fed from a container 10 to a passage 1 and led to a specimen introducing unit 2 with a specimen containing the decomposed products of tributyl phosphate. Then, a resultant mixed liquid is fed to a separating column 3 and the decomposed products are separated to tributyl phosphate TBP, dibutyl phosphate DBP, monobutyl phosphate MBP and phosphoric acid ions PO4<3->. The separated components are sequentially fed to a decomposing unit 4, added with an oxidation-decomposer 20 and decomposed by being irradiated with a microwave to be made the phosphoric acid ions PO4<3->. Thereafter, the phosphoric acid ions PO4<3-> are colored by adding a color coupler 16. TBP, DBP, MBP and PO4<3-> are detected in the order of separation while absorption peaks being temporally shifted. Accordingly, since the decomposed products of tributyl phosphate are analyzed without using a reference material, the decomposed products can be analyzed at the same time.
