Chemometric data analysis was applied to chromatographic data as a modeling tool to
identify the presence of solvents in gasoline obtained at gas stations in the Minas Gerais …

Unfortunately, addition of organic solvents (heavy aliphatic, light aliphatic and aromatic

The addition of organic solvents (light aliphatic, heavy aliphatic and aromatic hydrocarbons)
in Brazilian gasoline is unfortunately very frequent, and this illicit practice impares 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 …

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 …

Detection of adulteration in the petroleum fuels (gasoline and diesel) is challenging because
the adulterants usually include those compounds which are already present in these fuels …

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 …

Despite the action of ANP (National Agency of Petroleum Natural Gas and Biofuels) in the
process of monitoring and inspection, there are samples of gasoline being sold out of …

Hierarchical cluster and linear discriminant analysis, associated with physicochemical
assays, were used to identify the origin of gasoline commercialized in Brazilian gas stations …
