“…The normal column configuration is usually good for selecting out high polar components in the samples. Nevertheless, column configuration of polar to non-polar (reversed configuration) is reported to improve the resolution of individual alkanes, cyclokane, branched alkanes, and isoprenoids (Vendeuvre et al, 2005). www.intechopen.com DB-1MS).…”

“…While n-alkanes are among the most abundant individual components of diesel fuel (Gentner et al, 2012;Vendeuvre et al, 2005;Isaacman et al, 2012) and exhaust (Schauer et al, 1999), branched alkanes, cycloalkanes, and monoaromatic compounds are also very abundant and would be expected to be present in urban air, though rarely reported (Lewis et al, 2000). A new method is presented here to quantify the abundance of IVOC compounds using a thermal desorption sampler integrated into a proton transfer reaction mass spectrometer (PTR-MS).…”

Abstract.A method using thermal desorption sampling and analysis by proton transfer reaction mass spectrometry (PTR-MS) to measure long chain alkanes (C 12 -C 18 ) and other larger organics associated with diesel engine exhaust emissions is described. Long chain alkanes undergo dissociative proton transfer reactions forming a series of fragment ions with formula C n H 2n+1 . The PTR-MS is insensitive to nalkanes less than C 8 but displays an increasing sensitivity for larger alkanes. Fragment ion distribution and sensitivity is a function of drift conditions. At 80 Td the most abundant ion fragments from C 10 to C 16 n-alkanes were m/z 57, 71 and 85. The mass spectrum of gasoline and diesel fuel at 80 Td displayed ion group patterns that can be related to known fuel constituents, such as alkanes, alkylbenzenes and cycloalkanes, and other compound groups that are inferred from molecular weight distributions such as dihydronapthalenes and naphthenic monoaromatics. It is shown that thermal desorption sampling of gasoline and diesel engine exhausts at 80 Td allows for discrimination against volatile organic compounds, allowing for quantification of long chain alkanes from the abundance of C n H 2n+1 fragment ions. The total abundance of long chain alkanes in diesel engine exhaust was measured to be similar to the total abundance of C 1 -C 4 alkylbenzene compounds. The abundance patterns of compounds determined by thermal desorption sampling may allow for emission profiles to be developed to better quantify the relative contributions of diesel and gasoline exhaust emissions on organic compounds concentrations in urban air.

“…Esta técnica tiene hoy en día un lugar muy importante en la industria petrolera para el análisis de hidrocarburos ligeros, debido al alto poder de resolución que puede aportar (Ruiz-Guerrero et al, 2006;Vendeuvre et al, 2005a;Vendeuvre et al, 2005b;Wang et al, 2004). De manera general, las ventajas que resultan de la GC×GC son una resolución mejorada y alta sensibilidad, su principio y uso ha sido descrito (Vendeuvre et al, 2005b). Adicionalmente, el acoplamiento de la GC×GC a un detector especifico es una alternativa muy prometedora en la especiación de compuestos azufrados (Blomberg et al, 2003;Ruiz-Guerrero et al, 2006) ó nitrogenados (Adam et al, 2007;Wang et al, 2004), debido a que combina el alto poder resolutivo de la GC×GC y el aporte de una detección selectivas de azufre (GC×GC-SCD) o nitrógeno (GC×GC-NCD).…”

ResumenSe emplea la Cromatografía de Gases Bidimensional (GC×GC) como una poderosa herramienta en el análisis de derivados con azufre y nitrógeno presentes en gasolinas. Se presentan los resultados obtenidos del acoplamiento de la GC×GC a un detector especifico, azufre (SCD) y nitrógeno (NCD). La técnica se basa en la separación en dos dimensiones ortogonales que son el resultado de la asociación de dos columnas de GC de diferente polaridad. El cromatograma final obtenido ésta estructurado en función de las propiedades de volatilidad y polaridad de los hidrocarburos, lo que facilita su identificación. Los resultados son muy prometedores en la caracterización de éstos compuestos en mezclas complejas. En este trabajo se ilustra el potencial que tiene el alto poder resolutivo de la GC×GC combinado con una detección selectiva de azufre y nitrógeno en la caracterización de gasolinas al utilizar un detector especifico para éstos contaminantes. Palabras clave: cromatografía de gases bidimensional, detección específica, gasolina, nitrógeno, azufre Comprehensive Two-Dimensional Gas Chromatography Application in Sulphur and Nitrogen Speciation of Gasoline AbstractThe comprehensive two-dimensional gas chromatography (GC×GC) is used as a powerful tool for an improved characterization in sulphur and nitrogen speciation in gasoline. There are shown the results obtained of the connection between GC×GC and a specific detector, sulphur (SCD) and Nitrogen (NCD). This technique is based on the separation of two orthogonal dimensions, achieved by two chromatographic capillary columns with different polarity. The final chromatogram obtained was structured according to the volatility and polarity of hydrocarbons which facilitates its identification. The results are a very promising alternative in the characterization of these types of compounds in middle distillates. This work illustrates the high resolution power of the GC×GC in combination with a selective detection of sulphur or nitrogen compounds in gasoline when a specific detector is used.
