Abstract
Apparatuses, systems and methods for generating, dispersing and delivering chemical compounds utilizing desorption electrospray ionization. Embodiments include an airflow channel into which an airflow is directed, a solvent reservoir containing a volume of solvent, at least one charged droplet source for producing a plurality of charged liquid droplets in the channel, and at least one grounded counter electrode positioned within the channel with the electrodes having at least one surface containing one or more chemical compounds that include releasable ions. In operation, the charged droplets are directed onto the surface or surfaces so that the impact of the charged particles on said surface produces gaseous ions of at least one chemical compound on said surface, after which the gaseous ions are dispersed into the airflow.
