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 …

In brazil, gasoline is usually adulterated by diesel oil, ethanol (in addition to the amount
legally specified), petrochemical raffinates, and kerosene. This is an illegal action performed …

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 …

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 …

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 …
