Field desorption of ions from the tip to the meniscus of the liquid at the EHD-spraying

Investigated modes of operation and current characteristics of the device with a dynamic division electrospray flow sprayed liquid and removing the exess of the spray under normal conditions. The existence of three most typical spray patterns: electrospray, field desorption, flow. Demonstrated that the spray mode "field desorption" stability spraying currant and quantity not dependent on the flow of sprayed liquid in the range 50-200 µl/min.
