Abstract:
1. A method of detecting a concentration of a target component in a sample, including steps of: 1) defining a wavelength at which a light intensity is insensitive to variation of the target component concentration as a reference wavelength for the target component; 2) detecting spectra at the reference wavelength and a further measuring wavelength; 3) processing the spectrum detected at the further measuring wavelength, with the spectrum detected at the reference wavelength as an inner reference, to obtain a characteristic spectrum including specific information of the target component; 4) building a calibration model between the characteristic spectrum and the concentration of the target component; and 5) determining the concentration of the target component based on the calibration model, wherein the reference wavelength λ for a pure absorption sample, α for a scattering sample, wherein α
