1. An analytic nebulizer device for delivering a sample in aerosolized form, the device comprising:
a nebulizer nozzle configured to receive a flow of said sample and generate a plume of aerosolized sample spray; and
a chamber configured to receive a flow of make-up gas and fluidly coupled to a plurality of microchannels, wherein each of the microchannels comprises a microjet outlet, and wherein the microjet outlets are arranged around said nebulizer nozzle and are arranged substantially in a common plane;
wherein the nebulizer nozzle comprises a central axis and a nebulizer nozzle outlet;
wherein the nebulizer nozzle outlet is positioned within 5 mm of the common plane; and
wherein the microjet outlets are configured to direct said make-up gas stream substantially parallel to said central axis and to produce a make-up gas stream with high linear velocity around said aerosolized sample spray to shape and direct said plume.
