Abstract: The present invention relates to: a device (1, 101, 151) for separating off liquid and/or particulate contaminants from a gas flow (7, 107), in which a flow path of the gas flow (7, 107) runs between at least one first electrode (9, 31, 109) acting as a counter electrode and at least one second electrode (11, 111, 51, 53, 57, 135, 135′, 135″, 155) acting as an emitter electrode and having an electrode end (71, 77, 90) oriented in the direction of the first electrode, and a direct-current voltage exceeding the breakdown voltage can be applied between the first electrode (9, 31, 109) and the second electrode (11, 111, 51, 53, 57, 135, 135′, 135″, 155) in order to form a stable low-energy plasma (41, 125), wherein the second electrode (11) extends substantially along a first axis (X) in a first direction and the first electrode (31) has at least one plateau region (33) which is arranged opposite the second electrode (11) and which extends at least regionally in a first plane running substantially perpendicular to the first direction (X); and a method for operating such a device.
