Screening analysis to detect adulterations in Brazilian gasoline samples using distillation curves
(elservir, 2004)
Data on evaporated fraction temperatures obtained from the distillation curves of Brazilian gasolines were employed to identify
adulterated samples by applying the Soft Independent Modeling of Class Analogy (SIMCA) model. ...
Multivariate calibration in Fourier transform infrared spectrometry as a tool to detect adulterations in Brazilian gasoline
(2008)
In the present work, Fourier transform infrared spectroscopy (FTIR) in association with multivariate chemometrics classification
techniques was employed to identify gasoline samples adulterated with diesel oil, kerosene, ...
Screening Brazilian automotive gasoline quality through quantification of saturated hydrocarbons and anhydrous ethanol by gas chromatography and exploratory data analysis
(Vieweg, 2007-05-01)
In this paper a set of Brazilian commercial gasoline representative samples from São Paulo State, selected by HCA, plus six samples obtained directly from refineries were analysed by a high-sensitive gas chromatographic ...

Rapid and sensitive method for detecting adulterants in gasoline using ultra-fast gas chromatography and Partial Least Square Discriminant Analysis
(2018-03-01)
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 country. The impoverishment of the monitoring ...
Identification of gasoline adulteration using comprehensive two-dimensional gas chromatography combined to multivariate data processing
(Elsevier Science BvAmsterdamHolanda, 2008)
A sensor array based on mass and capacitance transducers for the detection of adulterated gasolines
(ELSEVIER SCIENCE SA, 2009)
The simultaneous use of different sensors technologies is an efficient method to increase the performance of chemical sensors systems. Among the available technologies, mass and capacitance transducers are particularly ...
