Notes:
Micellar electrokinetic chromatography/mass spectrometry (MEKC/MS) using an electrospray-chemical ionization (ES-CI) source is described. The interface between micellar electrokinetic chromatography and mass spectrometry consists of an electrospray-type nebulizer and an atmospheric pressure chemical ionization source that uses a needle electrode. Aromatic amines (aniline, p-nitroaniline, and 1-naphthylamine) are analysed by MEKC/MS, using a phosphate buffer that includes 20 mM sodium dodecyl sulfate (SDS), and protonated molecular ions of the samples are clearly recorded on the ion electropherograms. The results show that the ES-CI technique is very promising as an MEKC/MS interface since MEKC/MS uses a high concentration of nonvolatile salts and surfactants.
