제안 방법
- The compact and cost-effective miniaturized NIR system could relieve the economic burden for end-users. This study was based on a fairly simple chemical matrix. Future research will be directed to investigate its performance on highly complex chemical matrices such as refinery products (e.
- 16%. To validate the calibration model, three samples (3%, 5% and 7%) were prepared new each day and predicted over 5 days (totaling 15 spectra: 3 samples x 5 days). The concentration range from 3% to 7% was solely chosen for the prediction since the concentration variation is actually within this range.
대상 데이터
- 1 cm. The overall system included a tungsten halogen lamp as a light source, a photodiode array for micro-spectrograph, and an external power supply (or internal battery). The necessary software was installed for data collection.
- The spectra were collected using a fiber optic transflectance probe. The probe consisted of eight illuminating fibers, a receiving fiber, and a reflecting mirror. The distance between the optical fibers and the reflecting mirror was 1 mm, providing an actual pathlength of a 2 mm.
이론/모형
- A PLS regression and second derivative algorithm were performed using GRAMS/32 software with an add-on PLS algorithm (Galactic Industries Corporation, Salem, NH).
