    AnnotationThis work presents a new methodology for high-sensitivity analyses by capillary
    electrophoresis (CE) with electrospray-ionization mass spectrometric (ESI-MS)
    detection, based on electrophoretic focusing on an inverse electromigration dispersion
    (EMD) gradient. The technique is based on a robust electrolyte system providing a
    gradient of required properties, suitable for routine analyses of trace amounts of weak
    acids with pKa values between approx. 6.5 and 9. Examples analyses of several
    chlorophenols and sulfonamides are presented, with LODs around 3x10-9 M for spiked
    drinking water without any sample pretreatment.
