Abstract:
A nebulizer comprising:a passage through which a liquid flows, the passage including a capillary having an open tip, the liquid flowing through the capillary out of the open tip of the capillary;a gas passage which forms a gas flow around the open tip of the capillary, the gas flow spraying the liquid flowing out of the open tip of the capillary;a first electrode which contacts the liquid flowing in the passage and applies an electric potential to the liquid flowing in the passage; anda second electrode disposed around the capillary near the open tip of the capillary, the second electrode being downstream from the first electrode with respect to a direction in which the liquid flows in the passage, there being no gap extending downstream from the open tip of the capillary to the second electrode in a direction in which the liquid flows out of the open tip of the capillary, the second electrode being electrically isolated from the liquid flowing in the capillary and applying an electric field to the liquid flowing in the capillary.
