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 …

The desorption and ionization of analytes directly from surfaces or natural matrices under
ambient conditions has greatly simplified chemical analysis by mass spectrometry. Among …

This study has shown that the use of distillation curves combined with PCA (Principal
Component Analysis) and PLS-DA (Partial Least Squares Discriminant Analysis) provides a …

A simple and fast 1H NMR method, without any pretreatment, was developed for quality
control of gasoline. It is based on the average group molecular weight approach and relative …

Herein, a simplistic quartz crystal microbalance (QCM) approach for discrimination of
petroleum based fuels is presented. In this regard, a quartz crystal microbalance (QCM) …

The purpose of this study was to perform a discrimination and classification of diesel
samples from the four major suppliers of petroleum products in Morocco using Fourier …

The identification of gasoline adulteration by organic solvents is not an easy task, because
compounds that constitute the solvents are already in gasoline composition. In this work, the …

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 …

The identification of gasoline adulteration by organic solvents is not an easy task, because
compounds that constitute the solvents are already in gasoline composition. In this work, the …

The partial least-squares regression method (PLS) was employed to predict the amount of
ethanol and specific gravity in automotive gasoline using distillation curves (ASTM-D86) …
