Rapid determination of calcium in tobacco with near infrared spectroscopy
Qingzhou Tobacco Research Institute of CNTC, Qingzhou, Shandong, China
A mathematical prediction model of calcium in tobacco with FT-NIR spectrometry was established. The determination coefficient (R2) of the model was 92.00 and its root mean square error (RMSE) was 0.121 in cross validation, while the R2 and RMSE were...
