description To enable the concentration of each dissolved component to be measured, even when the state of a used component is unknown.SOLUTION: A first processing unit 102 identifies a use solution from the optical spectrum of the use solution measured by a spectroscopic measurer 101. The first processing unit 102 identifies a solution, as a use solution, of which the value substituted by the measured optical spectrum corresponds to a regression equation exceeding a set threshold. A second processing unit 103 finds, from the optical spectrum measured by the spectroscopic measurer 101, the concentration of each kind of known component of the solution identified by the first processing unit 102 on the basis of calibration information created on the basis of a reference solution that serves as a reference for the identified use solution.SELECTED DRAWING: Figure 1 【課題】用いられている成分の状態が不明であっても、溶解している各成分の濃度が測定できるようにする。【解決手段】第1処理部102は、分光測定器101が測定した使用溶液の分光スペクトルから、使用溶液を特定する。第1処理部102は、測定した分光スペクトルを代入した値が、設定されている閾値を超える回帰式に対応する溶液を、使用溶液として特定する。第2処理部103は、第1処理部102が特定した溶液の既知とされている成分の種類毎の濃度を、特定した使用溶液の基準となる基準溶液をもとにして作成した検量情報をもとに、分光測定器101が測定した分光スペクトルから求める。【選択図】 図1
