The present invention is an adjustable projectile target that includes a support structure that can hold a body portion of the target at various angular positions with regard to the support structure. An electrode rod is disposed at the center of the particle trap box, and the fine particles are electrically separated by applying a potential between the electrode rod and an electrode of the particle trap box. Utilizing an effort of sucking air through a nozzle, the particles of the therapeutic powder dose, made available to the nozzle, are gradually de-aggregated and dispersed into a stream of air entering the nozzle.
