Abstract
A measuring apparatus is provided with a light source (), a first light-receiving element () and a second light-receiving element () which output signals corresponding to light intensity, a calculating part () and a memory part (). The first light-receiving element () and the light source () are arranged so that transmitted light emitted from the light source and passed through a sample is received by the first light-receiving element (). The second light-receiving element () is arranged so as to receive light other than the transmitted light emitted from the light source (). In the memory part (), a correlation between the output value of the first light-receiving element () and the output value of the second light-receiving element () when light is emitted from the light source () in a state where the sample is not present is stored. The calculating part calculates absorbance of a target component contained in the sample, from the output values of the first light-receiving element () and the second light-receiving element () when light is emitted from the light resource () in the state where the sample present, and from the correlation.
