“…The response was found to be linear up to at least 500 ppmalthough at this concentration the signal was found to decay rapidly but to recover when the cell was flushed with nitrogen or air. A similar phenomenon has been reported for electrochemical fuel cell sensors, where the probable cause has been reported to be the slow removal of the polar reaction products, acetaldehyde and acetic acid, which can hydrogen bond to the electrode surface. It is most likely, since the partial oxidation of ethylene on gold produces acetaldehyde, that the slow removal of this reaction product is the cause of the signal decay.…”

“…A number of analytical techniques are available ranging from simple density measurements to modern techniques such as gas chromatography/ mass spectroscopy for identification of adulterants. The common testing methods for the fuels are density measurements, rate of evaporation, ash content determinations and viscosity measurements (Kalligeros et al, 2003), optical sensors (Bahari et al, 1992;Roy, 1999), spectroscopic methods (Canizares & de Castro, 1996;Patra & Mishra, 2001a,b, 2002Lima et al, 2004;Divya & Mishra, 2007;Al-Ghouti et al, 2008) and chromatographic (Pedroso et al, 2008) fingerprinting methods. Inclusion of different marker compounds such as dyes to the fuels can also be utilized for investigation of the levels of adulterants.…”

“…Many authors have studied adulteration of fuel, especially the addition of kerosene to diesel. Gasoline adulteration with kerosene was analyzed, and some techniques to detect it were proposed. Many authors have studied the adulteration of Brazilian gasoline with the addition of solvents. , …”
