Fast Determination of Denatured Fuel Ethanol Purity by Two-Dimensional Gas Chromatography Application

نویسنده

چکیده

Two-dimensional gas chromatography not only provides improved resolution, it can also provide much faster analysis times. A two-dimensional gas chromatography system based on a simplified Deans switch design is used to analyze the alcohol content in denatured fuel grade ethanol. By using two short columns of different selectivity, the two-dimensional gas chromatography application completes this analysis 10 times faster than the standard American Society for Testing and Materials D5501 method [1] without the use of cryogenic oven cooling. This easyto-use system also provides high qualitative and quantitative precision for this measurement.

Analysis of Denatured Fuel Ethanol using ASTM Method D5501-09

Denatured fuel ethanol is the feedstock used to make different types of high ethanol content motor fuels. Before it can be used, the amount of ethanol and methanol must be measured to assure product quality. ASTM method D5501-09 uses high resolution gas chromatography to perform this analysis. In this paper, the Agilent 7890A GC system was configured to run D5501-09. Excellent system performanc...

Two-dimensional gas chromatography analysis of components in fuel and fuel additives using a simplified heart-cutting GC system.

Multidimensional gas chromatography (MGC) using heart cutting is an old idea that can benefit from the performance of modern instruments and capillary columns to provide fast, reliable separation of target analytes from complex sample matrices. A simplified heart-cutting switch is described that uses these improvements to provide very narrow precise heart cuts between columns of different selec...

Determination of 2-phenylethanol in Rose Water Using Dispersive Liquid-Liquid Microextraction with Gas Chromatography Flame Ionization Detection

A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...

Determination of Residual Methylmethacrylate Monomerin Denture Base Resins by Gas Chromatography

Acrylic base resins are widely used in orthopedics and dental surgery. It is generally accepted that due to the incomplete conversion of methyl methacrylate (MMA) monomer to the polymer form during polymerization of the resin, some MMA monomers remain in the hardened material. MMA monomer has been reported to cause abnormalities or lesions in several organs of animals. Study of the literatures ...
