PURPOSE:To provide an analysis device for the concentrations of constituents of a mixture, capable of immediately measuring the concentrations of constituents at high accuracy using a near-infrared spectrophotometer. CONSTITUTION:An analysis device 1 for the concentrations of constituents of a mixture comprises a constituent concentration detecting portion 2 for detecting the concentrations of constituents of a mixture by means of a near-infrared spectrophotometer; a kind information storage portion 3 in which information about the reference concentration of each constituent, used for classifying the mixture according to its kind corresponding to the amounts of constituents mixed, is stored; a kind identifying portion 4 for identifying the kind of the mixture by comparing the reference concentration information with values detected by the constituent concentration detecting portion 2; a correction information storage portion 5 in which correction information derived from errors in the outputs of the near infrared spectrophotometer, which is determined for each kind of mixture, is stored according to the kind of mixture; and a correcting portion 6 for correcting the values detected by the constituent concentration detecting portion 2 for each kind of mixture, according to the correction information stored in the correction information storage portion 5. |
