MEKC has been used in conjunction with UV detection for identification and quantitation of high explosives in environmental samples. To ensure the compatibility of the technique with ESI‐MS, perfluorooctanoic acid (PFOA), a volatile micelle, was used. Separation of EPA Method 8330 Mixes A and B using various concentrations of the micelle showed that the 80 mM solution of PFOA was the optimum concentration...
Abstract. Capillary electrophoresis (CE) mass spectrometry (MS), with its ability to separate compounds present in extremely small volume samples rapidly, with high separation efficiency, and with compound identification capability based on molecular weight, is an extremely valuable analytical technique for the analysis of complex biological mixtures. The highest sensitivities and separation efficiencies...
