LIGHT SCATTERING TYPE COMPONENT CONCENTRATION MEASURING APPARATUS AND METHOD

摘要

PURPOSE:To provide a light scattering type component concentration measuring apparatus and method which enables non-destructive measurement of the concentration of a component in material to be measured using light in a near infrared wavelength area with better transmissivity and relatively low energy of light quantum. CONSTITUTION:This apparatus and method is made up of a light irradiation section 1 to irradiate material 16 to be measured with excitation light containing a near infrared wavelength area, a photodetecting section 2 which analyze a Raman scattered light from the material 16 to be measured to detect it and an arithmetic section 3 which calculates the concentration of a component in the material 16 to be measured from the quantity of the Raman scattered light to output the results of the calculation.
