Abstract
To quickly and accurately quantify four types of TSNAs contained in a tobacco raw material by using fluorescence fingerprint information, a tobacco raw material containing known quantities of four types of TSNAs is prepared, and fluorescence fingerprint information thereof is acquired. The fluorescence fingerprint information is pre-processed, as needed, and an estimation model (calibration curve) for estimating the total quantity of the four types of TSNAs from the fluorescence fingerprint information is created. After verifying the calibration curve, the total quantity of the four types of TSNAs contained in an unknown tobacco raw material is estimated by applying the calibration curve to the unknown tobacco raw material. On the basis of the estimated value of the total quantity of the four types of TSNAs and the known abundance ratios of the individual TSNAs, the contained quantities of the four types of TSNAs are estimated.
