  • Apparatus and method for controlling an electrostatically induced liquid spray
    Patent number: 7763848
    Abstract: A method for controlling an electrostatically induced liquid spray includes the steps of: (1) generating a liquid spray from a liquid sample with an electrostatic spray nozzle device using an applied electric field, wherein at least a nozzle portion of the spray device is formed of an insulating material; (2) sensing a current of the liquid spray with a spray current sensing means placed in relation to the spray device; (3) comparing the sensed current of the liquid spray with a pre-selected current value, with a difference between the two representing a control signal; and (4) varying the applied electric field using a computer-controlled positioning mechanism that moves the spray device relative to an inlet of the object that receives the liquid spray and acts as a counter-electrode.
