Abstract

A method for examining a culture solution containing a pH indicator and accommodated in a culture container includes: measuring, as a baseline intensity, an intensity of light that has passed through a solution and the culture container; measuring, as a measurement intensity, an intensity of light that has passed through the culture solution and the culture container; obtaining light source information including first information pertaining to the light source that is provided when measuring the baseline intensity and second information pertaining to the light source that is provided when measuring the measurement intensity; and on the basis of the baseline intensity, the measurement intensity, and the light source information, calculating an absorbance of the pH indicator at at least one wavelength included in emitted light from the light source.
