TY - JOUR PY - 2012// TI - Study on the best analysis spectral section of NIR to detect alcohol concentration based on SiPLS JO - Procedia engineering A1 - Wang, Xiaofei A1 - Bao, Yanfei A1 - Liu, Guili A1 - Li, Gang A1 - Lin, Ling SP - 2285 EP - 2290 VL - 29 IS - N2 - The alcohol concentration is usually measured through analyzing the multiple frequency absorption peak or cofrequency absorption peak of alcohol's C-H and O-H by NIRS. Based on the normalized transmittance spectrogram and Synergy interval partial least squares algorithm (SiPLS), the best analysis spectrum band detecting alcohol concentration is decided at the range of 1100nm-1330 nm and 2110nm-2400 nm or so, which is the second-harmonic peak of C-H and bending and expansion of vibration spectral section of C-H&O-H. The SiPLS model is established to analyzing 53 samples with different alcohol concentration, and obtained the root mean square error of prediction (RMSEP) is 0.0060, the correlation coefficient (R) is 0.9997, the better measuring result is obtained and this is hopeful be used to detect alcohol concentration during the Production process.
