High-performance liquid chromatography coupled off-line with capillary gas chromatography Application to the determination of the aromatics content in middle distillates

A New PVC-Activated Charcoal Fiber Coated on Silver Wire; Application in Determination of n-Alkanes in the Headspace of Soil Samples by SPME-GC

“…[1][2][3][4][5][6][7][8][9][10][11] In recent years, many advances have been made in the analysis of petroleum hydrocarbons. Capillary gas chromatography, [12][13][14] high-performance liquid chromatography coupled with gas chromatography, 15 sizeexclusion chromatography, [16][17][18] and many other advanced analytical methods have been used for this purpose. 19,20 Solid phase microextraction (SPME), which was first presented by Arthur and Pawliszyn in 1990, is a solvent-free alternative to the other common preconcentration and samplepreparation techniques.…”

Semi-micro solvent extraction as a rapid and efficient preconcentration technique for the determination of n-alkanes in oil-contaiminated water and soil samples by capillary gas chromatography

“…In recent years, major advances have been made in the techniques for oil analysis. Capillary gas chromatography [13 15], high-performance liquid chromatography coupled with gas chromatography [16], size exclusion chromatography [17 19] and other advanced analytical methods have been applied for this purpose [20,21].…”

Packed Column SFC of Gas Oils. Part II: Experimental Design Optimization of the Group-Type Analysis using CO2-SF6 as the Mobile Phase

“…On the one hand, the HPLC method has been successfully applied to commercial diesel fuels but some inaccuracy has been observed for some types of processed fuel (mildly hydrotreated fuels) due to the use of refractometric detection and the lack of representative external calibration [3]. On the other hand, the ASTM SFC method gives less information since group-type analysis of aromatic compounds is not achieved.…”
