ABSTRACT:
A system for controlling an electrostatically induced liquid spray includes an electrostatic spray device for generating a liquid spray from a liquid sample; a spray current sensing means placed in relation to the spray device and configured to generate a current output signal that represents a current of the liquid spray; and a mechanism that receives the current output signal and compares it to a pre-selected current value, with a difference between the two representing a control signal that is sent to one of (1) a pump that regulates the flow rate of the liquid sample and (2) a power supply to regulate an electric field associated with the spray device that generates the liquid spray according to a set level of current.
