Brazilian Canephora coffee evaluation using NIR spectroscopy and discriminant chemometric techniques. High-quality Brazilian Canephora coffees are rising to the level of specialty coffees in the face of a new industry perception. In this framework, spectra from 527 coffees were analyzed in the near-in... ... Repositório: BDPA Ano de publicação: 2023
Soil organic carbon determination using NIRS: evaluation of dichromate oxidation and dry combustion analysis as reference methods in multivariate calibration. Dichromate oxidation and dry combustion analysis were evaluated as reference methods to determine organic carbon in Brazilian soils using near infrared spectroscopy (NIRS) as an alternative. The main... ... Repositório: BDPA Ano de publicação: 2016
