Comprehensive Two-Dimensional Gas Chromatography for Detailed Characterisation of Petroleum Products
Comprehensive Two-Dimensional Gas Chromatography for Detailed Characterisation of Petroleum Products — Comprehensive two-dimensional gas chromatography (GC×GC) is a major advance for the detailed characterisation of petroleum products. This technique is based on two orthogonal dimensions of separation achieved by two chromatographic capillary columns of different chemistries and selectivities. ...
متن کاملComparison of conventional gas chromatography and comprehensive two-dimensional gas chromatography for the detailed analysis of petrochemical samples.
Comprehensive two-dimensional gas chromatography (GC x GC) has been investigated for the characterization of high valuable petrochemical samples from dehydrogenation of n-paraffins, Fischer-Tropsch and oligomerization processes. GC x GC separations, performed using a dual-jets CO2 modulator, were optimized using a test mixture representative of the hydrocarbons found in petrochemicals. For comp...
متن کاملInterpreting comprehensive two-dimensional gas chromatography using peak topography maps with application to petroleum forensics
BACKGROUND Comprehensive two-dimensional gas chromatography [Formula: see text] provides high-resolution separations across hundreds of compounds in a complex mixture, thus unlocking unprecedented information for intricate quantitative interpretation. We exploit this compound diversity across the [Formula: see text] topography to provide quantitative compound-cognizant interpretation beyond tar...
متن کاملComparative visualization for comprehensive two-dimensional gas chromatography.
This paper investigates methods for comparing datasets produced by comprehensive two-dimensional gas chromatography (GC x GC). Chemical comparisons are useful for process monitoring, sample classification or identification, correlative determinations, and other important tasks. GC x GC is a powerful new technology for chemical analysis, but methods for comparative visualization must address cha...
متن کاملInformation technologies for comprehensive two-dimensional gas chromatography
Comprehensive two-dimensional gas chromatography (GC GC) presents information technology challenges in data handling, visualization, processing, analysis and reporting. With its significantly greater separation capacity, GC GC generates data sets that are two to three orders-of-magnitude larger than for conventional GC and that exhibit an order-of-magnitude or more distinct peaks in complex mul...
