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 …

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 …

Unfortunately, addition of organic solvents (heavy aliphatic, light aliphatic and aromatic
hydrocarbons) in Brazilian gasoline is very frequent, and this illegal practice does not …

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 …

The addition of organic solvents (heavy aliphatic, light aliphatic and aromatic hydrocarbons)
in Brazilian gasoline is unfortunately very frequent, and this illicit practice does not …

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

To find out if gasoline is adulterated, it is essential to analyze the sample's information
efficiently; however, current official test methods are time consuming and costly. Much …

In this work, flame emission spectroscopy (FES) was combined with the partial least squares
discriminant analysis (PLS-DA) method aimed at classifying different types of gasoline …

A method to detect potential adulteration of commercial gasoline (Type C gasoline, available
in Brazil and containing 25%(v/v) ethanol) is presented here. Comprehensive two …

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 …
