Abstract
A feedback control system for an electrospray nozzle and counter-electrode, comprising a source of light which intersects, one or snore of the liquid cone, jet and plume of the fluid exiting the nozzle, one or more photo detectors to detect light patterns and generate photo-electronic signals in response thereto, an electronic detection and amplification system to convert the photo-electronic signals to electronic signals, a computer or micro-processor to interpret said electronic signals and a second computer or microprocessor to communicate with the first computer and generate a signal to a controller which adjusts the electric field surrounding the nozzle either by changing the distance between the nozzle and counter-electrode or changing the voltage of the nozzle or counter-electrode.
