Analysis of Hydrocarbon Mixtures by Capillary Gas-Chromatography

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...

Capillary Column Selectivity and Inertness for Sulfur Gas Analysis in Light Hydrocarbon Streams by Gas Chromatography

Characterization and Evaluation of Light Hydrocarbon in Northwestern Iranian Crude Oil by Detailed Hydrocarbon Analysis (D.H.A)Gas Chromatography

Lighthydrocarbons are commonly used to evaluatecrude oils to determine oil families in reservoirs undergone some kind of alteration process. In this study crude oil contentsfromNorthwestern IranDelta (samples A, B and C)were analyzed in order to evaluate the IranDelta petroleum system independent of higher molecular weight markers. Ultra high resolution gas chromatography was used in separation...

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 ...

Anaesthetic Mixtures: Gas Chromatography

acids and peptides due to the manifold separation modes that can be applied. Short analysis times, easy manipulation of separation conditions and small injection volumes (nanolitres) are further advantages. The Reld of biomedical and clinical amino acid and peptide analysis is still under investigation, especially as the transfer and adaptation of the separation modes to a broader range of real...
