title: Extractive electrospray ionization for direct analysis of undiluted urine, milk and other complex mixtures without sample preparation.
abstract: On-line droplet-droplet extraction occurs when a sample spray intersects a reagent electrospray; this allows continuous analysis of trace amounts of compounds directly in complex matrices including undiluted urine, milk and polluted water over extended periods of time.
