Abstract: PROBLEM TO BE SOLVED: To improve a function of an electro spray device disposed so that a spray needle and an ion extraction interface become orthogonal to each other.
SOLUTION: An interface axis 122 is disposed in a relationship so as to cross a spray nozzle axis 124, an angle defined between the nozzle axis 124 and the interface axis 122 are set from around 75 ° and around 105 °. An interface 106 is possible to operate to accept a voltage from an interface power source, and an auxiliary electrode 140 can operate for accepting a voltage from an auxiliary power source. The electrode 140 can operate, to regulate electric field at an outlet orifice and disposed in a relationship possible to operate against the orifice. The electro spray device can operate to define an ion passage, through which ions on their ways from the orifice to an inlet are passed and the electrode 140 is disposed outside the ion passage.
