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 the 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.
