| dc.description.abstract | Fourier Transform Infrared (FTIR) spectroscopy focused on the near infrared (NIR) region has become crucial for quality control on diverse areas, from energy to biomedical applications, by enabling in-situ and in real time analysis of samples with complex organic compositions [1,2]. The development of portable and miniaturized NIR spectrometers (miniNIR) can further extend NIR spectroscopy applications [3,4], thus this work compares in-situ analysis based on a FT-NIR benchtop spectrometer with a miniNIR prototype to detect and quantify contaminants in biodiesel, such as vegetable oils, methanol, and glycerol. Good models based on principal component analysis-linear discriminant analysis of FT-NIR spectra were obtained, predicting contaminants with accuracies between 75 to 95%, while the miniNIR prototype’s delivered models with accuracies between 66 to 86%, showing the device’s potential for preliminary quality control of biodiesel, with the added advantages of low cost and portability. | pt_PT |
