Abstract:
1. An apparatus for generating, dispersing and delivering chemical compounds utilizing desorption electrospray ionization comprising: an airflow channel into which an airflow is directed; a solvent reservoir containing a volume of solvent; one or more arrays of electrospray sources in communication with said solvent reservoir for producing a plurality of charged liquid droplets in said airflow channel; one or more grounded counter electrodes positioned within said airflow channel, said electrodes having at least one surface containing one or more chemical compounds with releasable ions; wherein the voltage between said one or more grounded counter electrodes and said charged droplet source is sufficient to maintain an electric field sufficient to sustain an electrospray process in said airflow channel; wherein said charged droplets are directed onto said surface so that the impact of the charged particles on said surface produces gaseous ions from said surface; and wherein said gaseous ions are dispersed into the airflow and directed out of said electric field region.
