Abstract This study aimed to apply the near infrared reflectance spectroscopy (NIRS) for a robust and fast detection method fraudulence in patchouli oil plant. Pure sample adulterated with ethanol were used as samples this work. Spectral data form of transmittance acquired wavenumbers range from 400 4000 cm −1 . A total 60 mixed using six difference concentration while 10 remaining pure without...

Abstract Stable isotopes analysis (SIA) of carbon and nitrogen provides valuable information about trophic interactions animal feeding habits. We used near‐infrared reflectance spectroscopy (NIRS) support vector machines (SVM) to develop a model for screening isotopic ratios ( δ 13 C 15 N) in samples from living animals. applied this method on dried blood birds previously analyzed N test whethe...

The application of near infrared spectroscopic technique for the quantitative analysis of food products and commodities is nowadays widely accepted. However, 160 years passed from the discover of near infrared part of the spectrum to its first analytical application which is related to the work of Karl Norris who firstly demonstrated the potential of the NIRS in quantitative analysis particular...

For fast detection of inorganic phosphorus fractions and their phosphorus contents in soil, a method employing near-infrared spectroscopy (NIRS) combined with partial least squares (PLS) and least squares support vector machine (LS-SVM) was proposed. Fifty soil samples for each of iron phosphate, magnesium phosphate, calcium phosphate and aluminum phosphate, with application rates of phosphate ...
