Abstract: This study compares the performances of two mass-spectrometric ionization techniques, i.e. fast-atom bombardment (FAB) and ion-spray ionization (ISI), in the simultaneous quantitation of dodecyl-, tetradecyl- and hexadecyltrimethylammonium halides in aqueous media. Continuous-flow FAB and flow injection analysis (FIA)-ISI, both in selected-ion monitoring and selected-reaction monitoring modes, were evaluated. Quantitation was performed by dilution with deuterium-labeled homologues synthesized by a simple procedure. A comparison of the data indicated FIA-ISI as the more sensitive (limit of detection = 10 ppb). Good linearity, precision and accuracy were obtained by the tested techniques in the concentration. range 0.125-4.0 ng µL-1. Hair softeners, commercial surfactant mixtures and hematol. lysing reagents were used as test samples.
