Determination of Free Fatty Acids from Soil by LC–MS with Fluorescence Detection and Atmospheric Pressure Chemical Ionization Identification

A simple and highly sensitive method for the determination of fatty acids using liquid chromatography with fluorescence detection is described. Fatty acids were derivatized by a new novel pre-column derivatization reagent 1,2-benzo-3,4-dihydrocarbazole-9-ethanol before injection.

Glycan labeling strategies and their use in identification and quantification

Most methods for the analysis of oligosaccharides from biological sources require a glycan derivatization step: glycans may be derivatized to introduce a chromophore or fluorophore, facilitating detection after chromatographic or electrophoretic separation.

N-Alkylpyridinium isotope quaternization for matrix-assisted laser desorption/ionization Fourier transform mass spectrometric analysis of cholesterol and fatty alcohols in human hair

Isotope-coded reagents have been developed for labeling of amino acids, phenols and fatty acids, but not for alcohols. In this work, a simple reaction based on direct N-alkylpyridinium isotope quaternization (NAPIQ) was developed for mild derivatization of cholesterol and fatty alcohols.
