A method of analyzing a liquid sample by applying the sample to a composite test paper composed of a strip plastic transparent film and a reflectivity reference or compensation paper piece and a plurality of color reaction test paper pieces affixed to the strip, feeding the test paper to a spectral reflectivity measuring device a predetermined period of time after the application, and calculating the corrected reflectivities of each of the paper pieces from the measured amounts of reflected light at varying wavelengths to determine the concentration of the abnormal substance contained in the test sample, free of measuring errors due to the color if any of the sample, differences in the color developed and variations in the thickness of the color reaction test paper pieces and reflectivity reference or compensation paper piece. A system for practicing this method is also disclosed.

A method of analyzing a liquid sample comprising the steps of applying the sample to a composite test medium formed of a strip having thereon a reflectivity reference piece and at least one color reaction test piece feeding the test medium to spectral reflectivity measuring means, irradiating each of the pieces with energy of a plurality of predetermined different wavelengths, and obtaining corrected reflectivities of each of the test pieces as the relative values with respect to the reflectivity of said reflectivity reference piece from the amounts of reflected energy at at least some of the different wavelengths to measure the concentration of an abnormal substance contained in the test sample.
