In the present work, Fourier transform infrared spectroscopy (FTIR) in association with
multivariate chemometrics classification techniques was employed to identify gasoline …

In this work, transform-infrared spectroscopy (FTIR) was associated with chemometric tools,
especially principal component analysis (PCA) and partial least squares regression (PLSR) …

This work presents a low cost system based on Flame Emission Spectroscopy (FES) that
enables the prediction of fuel adulteration. The spectral data acquired using FES were …

The criminal act of fuel (gasoline) adulteration still remains a global worry due to its
environmental, health and economic effect. Current methods for the detection of fuel …

Brazilian automotive gasoline has been the target of constant adulterations in an attempt to
raise profit margins as a result of the market flexibility and the ensuing increased …

Fourier transform infrared spectroscopy (FTIR) coupled to chemometrics techniques was
used to investigate high quality motor oils samples adulterated with lower quality oils, like …

In the last years, the Brazilian Fuel Quality Monitoring Program drastically reduced the
number of analyzed fuel samples as consequence of the current economic crisis in the …

In this paper, an attempt has been made to develop a feasible procedure for the prediction of
quality parameters of motor gasoline and to discriminate between the different adulterated …

This work presents the potentiality of partial least squares discriminant analysis (PLS-DA)
associated with mid-infrared spectroscopy to detect gasoline, residual automotive lubricant …

The smuggling of products across the border regions of many countries is a practice to be
fought. Brazilian authorities are increasingly worried about the illicit trade of fuels along the …
