Determination of Hydroperoxide Content in Complex Hydrocarbon Mixtures by Gas Chromatography/Mass Spectrometry

Determination of hydroperoxide content in complex hydrocarbon mixtures by gas chromatography/mass spectrometry.

A known principle in which triphenylphosphine is allowed to be oxidized by hydroperoxides to triphenylphosphine oxide, was developed into an analytical method for determination of hydroperoxide content in light mineral oils using GCMS-detection and quantification. By suitable choice of reagent solution solvents and internal standard, the method proved to be simple to apply and very rugged. For ...

Quantitative Analysis of Aromatic Hydrocarbons in Complex Hydrocarbon Mixtures by High Resolution Capillary Gas Chromatography

Natural and synthetic hydrocarbon mixtures are complex samples containing hundreds of different aliphatic and aromatic components in widely differing concentrations. The number of components depends on a group-type composition and the range and distribution of boiling points of the components present in the mixture . Hydrocarbon mixtures are characterised in two ways, by structural group analys...

Improved resolution of hydrocarbon structures and constitutional isomers in complex mixtures using gas chromatography-vacuum ultraviolet-mass spectrometry.

Understanding the composition of complex hydrocarbon mixtures is important for environmental studies in a variety of fields, but many prevalent compounds cannot be confidently identified using traditional gas chromatography/mass spectrometry (GC/MS) techniques. This work uses vacuum-ultraviolet (VUV) ionization to elucidate the structures of a traditionally "unresolved complex mixture" by separ...

Organic compounds present in the natural Amazonian aerosol: Characterization by gas chromatographymass spectrometry

[1] As part of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA)Cooperative LBA Airborne Regional Experiment (CLAIRE) 2001 campaign in July 2001, separate day and nighttime aerosol samples were collected at a ground-based site in Amazonia, Brazil, in order to examine the composition and temporal variability of the natural ‘‘background’’ aerosol. We used a high-volume sampler to ...
