Notizen:
A fused-silica capillary high-performance liquid chromatography column (i.d. 0.25 mm) packed with octadecylsilane-bonded silica has been used on-line with continuous-flow negative-ion fast-atom bombardment (FAB) mass spectrometry for the separation and structural analysis of series of fatty acids and arachidonic acid metabolites derivatized with 4-aminobenzenesulphonic acid. Negative-ion FAB spectra of the derivatized lipids showed strong [M—H]- pseudomolecular ions. Collision-induced dissociation of these anions produced structurally informative daughter ions, arising from charge-remote fragmentations.
