MEASURING APPARATUS

PROBLEM TO BE SOLVED: To provide a measuring apparatus for calibrating the optical noise caused by the surface roughness (irregularities) of a biosensor. SOLUTION: The measuring apparatus 110 is a measuring apparatus for (a) performing chromatography measurement with respect to the sample spotted on the biosensor 120 and equipped with a photographing unit (a light emitting device 111, an iris 112, a condensing lens 113, a photodetector 114 and a signal converting part 115) for (b) photographing the measuring part (a developing part 122 and a reaction part 123) of the biosensor 120 to form the image signal of the measuring part, a control part 119 for (c) controlling the photographing unit to allow the photographing unit to photograph the measuring part before and after the sample is developed on the measuring part and an image processing part 116 for (d) using the image signal formed by the photographing unit before the sample is developed on the measuring part to remove the noise component inherent to each biosensor contained in the image signal formed by the photographing unit after the sample is developed on the measuring part.
