Classification: CPC G  A | IPC G

Claim 15:
16. An apparatus comprising:
an inference model creating means that inputs fluorescence fingerprint information consisting of excitation wavelength, fluorescent wavelength, and fluorescence intensity data of tobacco raw materials which contain four kinds of tobacco-specific nitrosamines (TSNAs) which are NNN, NNK, NAT, and NAB, and obtains a calibration curve by setting the fluorescence fingerprint information as an explanatory variable and setting total amount of the contained four kinds of TSNAs, that are calculated from values of known quantities of the four kinds of TSNAs contained in the tobacco raw materials, as a response variable;
a total amount inferring means for inferring a total amount of the four kinds of TSNAs contained in the tobacco raw materials, based on the calibration curve and fluorescence fingerprint information of tobacco raw materials which contain unknown quantities of the four kinds of TSNAs; and
a contained quantity inferring means for inferring the contained quantities of the four kinds of TSNAs, based on the inferred total amount of the four kinds of TSNAs and a known abundance ratio among the four kinds of TSNAs.
