Abstract
A measuring method of determining component concentration in a solution by calculating component concentrations in the solution at various temperatures in a small number of steps. The component concentration is measured at an arbitrary temperature T by using a solution absorbance spectrum and solvent absorbance spectrum at a plurality of wavelength(s)r, and preliminarily determining a calibration coefficient M(T). Concentration of Cof component i in solution at reference temperature T, is obtained at differential spectrum of solution spectrum S (λ, T) at temperature T in j-th wavelength λand solvent spectrum B (λ, T) at temperature T in j-th wavelength λ, calculating calibration coefficient M(T) the specific component concentrations.
