Abstract
An apparatus includes a portable housing and a plurality of separately operable microfluidic emitters disposed within the housing. Each microfluidic emitter h an inlet for receiving a liquid and an outlet for emitting a spray. Each microfluidic emitter is movable within the portable housing between a first position in which the outlet of that microfluidic emitter is fully retracted within the portable housing and a second position in which the outlet of that microfluidic emitter projects out of the portable housing. The portable housing with the multiple emitters is adapted to be detachably coupled to another housing portion. This housing portion includes a microfluidic substrate with a channel for transporting an eluent and an outlet aperture for emitting the eluent. The inlet of one of the emitters is detachably coupled to the outlet aperture of the microfluidic substrate.
