As the world’s remaining deposits of petroleum become heavier it's important to understand the chemical nature of heavy crude oil and its fractions. The analysis of high boiling point constituents of ...

are often small peaks in a GC chromatogram that can easily be obscured in a 1D-GC analysis (Figure 5). Figure 5. GCxGC-TOFMS contour plot of a tar ball sample and suspected crude oil source. Extracted ...

Laboratory crude-oil degradation experiments were set up ... microcosms and analysed for carbon dioxide and methane using gas chromatography-mass spectrometry (GC-MS). After removal of an aliquot ...

Monitoring the quality of essential oils is vital for protecting consumer health. Researchers recently combined gas chromatography and mass spectrometry approaches to gather data on mandarin essential ...

The goals include authentication, quality control or general characterization for deeper learning of chemical composition in the essential oil and to identify the best way to use them in a product or ...

The growth in Gas Chromatograph market is driven by the increasing adoption of GC-MS, rising crude & shale oil production, increasing importance of wastewater treatment, rising food safety concerns, ...
