    Highly sensitive analysis of chlorophenols and sulfonamides in waters by electrophoretic focusion on inverse electromigration dispersion gradient with ESI-MS detection

  • Original language description

    This work presents a new methodology for high-sensitivity analyses by capillarynelectrophoresis (CE) with electrospray-ionization mass spectrometric (ESI-MS)ndetection, based on electrophoretic focusing on an inverse electromigration dispersionn(EMD) gradient. The technique is based on a robust electrolyte system providing angradient of required properties, suitable for routine analyses of trace amounts of weaknacids with pKa values between approx. 6.5 and 9. Examples analyses of severalnchlorophenols and sulfonamides are presented, with LODs around 3x10-9 M for spikedndrinking water without any sample pretreatment.
