Determination of ethanol in gasoline by high-performance liquid chromatography

A Novel Amperometric Biosensor Based on Poly(allylamine hydrochloride) for Determination of Ethanol in Beverages

“…For these reasons, ethanol detection is of great importance for clinical and industrial applications. Some of the most common detection methods for ethanol include high performance liquid chromatography [ 1 ], gas chromatography [ 2 ], capillary electrophoresis [ 3 ], colorimetry [ 4 ], Raman spectrometry [ 5 ], or tandem techniques [ 6 , 7 ]. Although some of the above methods are complex and reliable, they can have disadvantages such as the need to use previous processes of sample separation (distillation, pervaporation), can be time consuming, and instruments can be expensive and need trained operators.…”

Applications of High Performance Liquid Chromatography in the Petroleomic Analysis of Crude Oil: A Mini-Review

“…Nonaqueous reversed phase HPLC, where a nonpolar column is used with organic solvents, was also used to accurately measure ethanol in gasoline via an RI detector. 80 This approach yielded an ethanol peak that was free from coelution of other components in the gasoline, with excellent analytical figures of merit.…”

“…In this case, the authors tried many LC and GC combinations, and found that LC fraction collection followed by GC measurement gave the best results. Nonaqueous reversed phase HPLC, where a nonpolar column is used with organic solvents, was also used to accurately measure ethanol in gasoline via an RI detector . This approach yielded an ethanol peak that was free from coelution of other components in the gasoline, with excellent analytical figures of merit.…”

A 3D-Printed Breath Analyzer Incorporating CeO2 Nanoparticles for Colorimetric Enzyme-Based Ethanol Sensing

“…Alcohol detection is also important for a number of industries, like food quality monitoring and food authenticity, for halal food certification, 3 assessing progress of fermentation processes, 4,5 and for detecting alcohol in breast milk to avoid harming infants. 6 Alcohol quantification is performed by benchtop instrumentation such as redox titrations, 7 refractometry, 8 high performance liquid chromatography, 9 near-infrared spectroscopy 10 and gas chromatography. 11,12 To achieve the full potential of breath analysis and avoid the limitations of sample preparation in conventional methods, simple user-friendly methods that can be used on site and at homes are desired.…”

“…Alcohol quantification is performed by benchtop instrumentation such as redox titrations, refractometry, high performance liquid chromatography, near-infrared spectroscopy and gas chromatography. , To achieve the full potential of breath analysis and avoid the limitations of sample preparation in conventional methods, simple user-friendly methods that can be used on site and at homes are desired. Commercial breathalyzers that measure the concentration of ethanol use ethanol-sensitive dyes such as potassium dichromate; however, these detectors have limited reliability, and accurate detection of alcohol intoxication still rely on blood analysis.…”
