Abstract:
Described are an apparatus for generating and collecting nanospray reactive droplets and a method for analyzing a protein digestion. The apparatus includes a capillary, counter electrode, collection vessel, electrostatic lenses, and voltage control module. The capillary receives a mixture that includes a protein and an enzyme and has an outlet disposed in the aperture to dispense the mixture. The collection vessel has a concave surface to receive a nanospray plume emitted from the capillary outlet. The counter electrode and electrostatic lenses are disposed along a nanospray path defined between the capillary outlet and the collection vessel. Each electrostatic lens is formed of an electrically conductive plate having an aperture therein to pass a nanospray reactive plume. The voltage control module is in electrical communication with and is configured to independently control the voltage of the capillary, the counter electrode, the collection vessel and each of the electrostatic lenses.
Abstract:
An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure air stream and passes the fluid through an electrode inside a nozzle assembly to charge, such as negatively charge, droplets of the atomized fluid. The system uses a unique nozzle design that is configured to optimally atomize the fluid into various sized droplets.

Abstract:
An electrostatic coater capable of realizing high-level coating quality is provided. Shaping air SA, discharged from an air port, is directed radially outward. An elevation angle thereof preferably ranges from 10 to 20 degrees. Further, the shaping air SA is a flow in a state of being twisted in a direction opposite to the rotation direction R of a bell cup. The twisting angle about the axis O of the bell cup preferably ranges from 38 to 60 degrees. A liquid thread of paint extends radially outward from the outer peripheral edge of the bell cup, and the paint separated from the tip end thereof becomes a particle. It is preferable that the shaping air SA collides with the paint particle at a point P where the momentum of the paint particle is decreased of the paint particle is decreased.
Abstract:
A system to apply mainly phytosanitary products that use the principle of electrostatic attraction. A high static charge is imprinted on the microdrops in the nozzle with high flows of water using a simple industrial design and very low probabilities of failure. The system is very stable and reliable. An active water provider capillary tube is optionally used in the nozzles (as opposed to a fixed one), which results in a more efficient use of the air to micronize drops. The nozzles can be fixed or dirigible nozzles. A chemical product doser system is optionally used with injection in the nozzle itself.
