<p><P>PROBLEM TO BE SOLVED: To provide an analytical method and an analyzer capable of reducing measurement errors due to the dependency of optical filters on the angle of incidence. <P>SOLUTION: Light from a specimen 2 carried by a test strip 3 is passed through an optical system having an optical filter 6 and received by an image sensor 7 provided with a plurality of pixels to acquire concentration information of the specimen in the analytical method. The angleθof the filter incidence incident onto the optical filter 6 of the light which forms an image in the pixels A is computed. The amount of shift of the filter band of the optical filter 6 corresponding to the angleθof the filter incidence is acquired to acquire a correction coefficient corresponding to the amount of shift. The correction coefficient is used to correct luminance. Concentration information of the specimen 2 is acquired on the basis of this corrected luminance value. Since it is possible to reduce measurement errors due to the dependency of the optical filter 6 on the angle of incidence by this analytical method, measurement accuracy and reliability at the time of analyzing the specimen 2 are improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
