Abstract
An apparatus and a method for measuring concentrations of components with light scattering allows measurement of concentrations of components in a measuring object to be accomplished in non-destructive fashion by using light in near-infrared wavelength ranges with good transmissivity and relatively low light quantum energy. The apparatus is composed of a light irradiator (1) for irradiating excited light in a near-infrared wavelength range to a measuring object (16), a photodetector (2) for receiving and spectrally separating Raman scattered light derived from the measuring object (16), and an arithmetic unit (3) for calculating concentration of a component in the measuring object (16) from intensity of the Raman scattered light and outputting a calculation result.
