Abstract (en)

[origin: EP2251086A2] The method involves activating an electric surface discharge at a wall of a central channel that is flowed-through by a gaseous medium by application of variable high-voltage to an excitation electrode (2), such that ions are produced in the gaseous medium under field-free conditions. The electrode is separated from a wall electrode (4) and a flow channel (5) by a dielectric (1), and voltage impulse is applied to the excitation electrode, where passages are formed between the wall electrode and the dielectric. An independent claim is also included for a device for neutralization of gas-carried particles or for generation of bipolar ion atmosphere for an ion mobility spectroscopy.
