Validation of a one-step extraction/methylation method for determination of fatty acids and cholesterol in marine tissues.
A simple and fast direct extraction/methylation with methanolic hydrogen chloride was validated for determination of fatty acids (FA) in marine tissues and gave a higher recovery of the total FA than the traditional procedure. Expand
Identification of estrogen-like alkylphenols in produced water from offshore oil installations.
This work focuses on the analysis and identification of phenols in produced water, in particular long-chain para-substituted alkylphenols, which act as endocrine disruptors for marine biota. Expand
Determination of trans double bonds in polyunsaturated fatty acid methyl esters from their electron impact mass spectra
The geometrical isomers of unsaturated fatty acid methyl esters were analysed by gas chromatography — electron impact mass spectrometry. Distinct differences in the electron impact mass spectra ofExpand
Metabolic markers in blood can separate prostate cancer from benign prostatic hyperplasia
Changes in fatty acid (acylcarnitines), choline (glycerophospholipids) and amino acid metabolism (arginine) as markers for PCa compared with BPH are suggested. Expand
Bioprospecting North Atlantic microalgae with fast growth and high polyunsaturated fatty acid (PUFA) content for microalgae-based technologies
A screening pipeline is designed, targeting a focused search and selection for marine microalgal strains from extreme North Atlantic locations with high robustness and biomass production, and increased levels of EPA and DHA. Expand
The prediction of fatty acid structure from selected ions in electron impact mass spectra of fatty acid methyl esters
The possibility of fatty acid identification from ions in the mass region of 50–110 amu in electron impact mass spectra has been studied by application of various multivariate techniques. The focusExpand

A method for the identification of fatty acid methyl esters (FAME) based on the analysis of shifts in equivalent chain lengths (ECL), which is suitable for determination of the number of trans and cis double bonds in trans fatty acids, and for detection of artefacts in fatty acidmethyl ester chromatograms. Expand
Prediction of gas chromatographic retention of polyunsaturated fatty acid methyl esters.
Multivariate regression models were applied to predict retention indices as equivalent chain lengths (ECL) for methylene-interrupted polyunsaturated fatty acids. Simple molecular descriptors, theExpand
Comparing EPA production and fatty acid profiles of three Phaeodactylum tricornutum strains under western Norwegian climate conditions
Looking at the potential of the climate conditions in Bergen, western Norway for outdoor cultivation of P. tricornutum in flat panel photobioreactors and cultivated three different strains simultaneously revealed more significant differences between outdoor and laboratory-grown cultures than between the strains, and higher EPA contents in outdoor grown cultures.

Optimizing the relationship between chromatographic efficiency and retention times in temperature-programmed gas chromatography.
A methodology that can maximise the chromatographic efficiency that can be achieved within a defined time frame in temperature-programmed gas chromatography is described, and optimal conditions are found by combining the two models. Expand
