<p>PROBLEM TO BE SOLVED: To improve the accuracy of odor intensity and to realize a display allowing odor characteristics to be easily grasped sensuously. SOLUTION: A storage part 1 stores the functional value data of plural kinds of reference samples with the known functional values to odor intensity and plural kinds of odor qualities, and signal peak intensity data when measuring the reference samples, as reference data. On the basis of the reference data, an odor intensity computing part 3 computes a relational expression on odor intensity using a multiple regression analysis or a main component analysis, and an odor quality computing part 5 computes a relational expression on plural kinds of odor qualities using a neural network. A display part 7 displays the odor intensity on a first axis and the values on one or two kinds of selected odor qualities on a second axis, or the second axis and a third axis.</p> |
