    Abstract: A calibration curve setting method used at the time of quantitatively analyzing specific components in a drug by a transmission Raman spectrum, the method comprising the steps of: obtaining respective transmission Raman spectra of a plurality of different wave number ranges including Raman hands corresponding to the specific components of a plurality of known drugs of which concentrations or amounts of the specific components are known and the concentrations or the amounts are different from each other; calculating candidate calibration curves which are candidates for calibration curves used for the quantitative analysis respectively from a plurality of transmission. Raman spectra in each of the wave number ranges; and using the most probable candidate calibration curve as a calibration curve for the quantitative analysis of the specific components, among the respective candidate calibration curves.
