ABSTRACT:
By using an imaging device (30), it is possible to determine the concentration of flourescent pigments contained in a target sample (1). The imaging device has a plurality of detection wavelength bands. There are prepared a plurality of reference samples, each containing each of the flourescent pigments in a predetermined unit concentration, so as to obtain measurement intensity of flourescent light emitted from each reference sample at each detection wavelength band. The flourescent image of the target sample is imaged at each detection wavelength band by using the imaging device. By using the flourescent intensities obtained from the reference sample and the target sample, calculation is executed so as to obtain the concentration of each of the flourescent pigments in the target sample.
