| 摘要 | A concentration measurement method by an absorptiometric method which measures a concentration of a first solute component dissolved in a solution, in which the first solute component interacts with a solvent, includes: referring to an absorption coefficient (μaw(λ)) of the solvent; measuring an absorption coefficient (μa(λ)) of a first sample material, after an interaction between the solvent and the first solute component has occurred; and obtaining an unknown volume fraction (vg) of the first solute component and a volume fraction (vw) of the solvent, based on the absorption coefficient (μaw(λ)) of the solvent, a apparent absorption coefficient (μ′ag(λ)) of the first solute component, and the absorption coefficient (μa(λ)) of the first sample material. | ||

| 主权项 | 1. A concentration measurement method by an absorptiometric method which measures a concentration of a first solute component dissolved in a solution, in which the first solute component interacts with a solvent, comprising: referring to an absorption coefficient (μaw(λ)) of the solvent; referring to an apparent absorption coefficient (μ′ag(λ)) of the first solute component, which is measured in advance, after an interaction between the solvent and the first solute component has occurred; measuring an absorption coefficient (μa(λ)) of a first sample material, after the interaction between the solvent and the first solute component has occurred; and obtaining an unknown volume fraction (vg) of the first solute component and a volume fraction (vw) of the solvent, based on the absorption coefficient (μaw(λ)) of the solvent, the apparent absorption coefficient (μ′ag(λ)) of the first solute component, and the absorption coefficient (μa(λ)) of the first sample material, by solving a system of instances of Equation 1 applied to two different wavelengths, or by solving a system of Equation 1 applied to one wavelength and Equation 2 μa(λ)=μ′ag(λ)·vg+μaw(λ)·vw (Equation 1)vg+vw=1 (Equation 2). | ||
