Abstract
Systems and techniques for cleaning a corona discharge point are described. A controller () can be operatively coupled to a corona discharge point () to control the operation of the corona discharge point (. The controller () and the corona discharge point () can be included with, for example, an ion mobility spectrometry (IMS) system (). The controller () can be used to operate the corona discharge point () at an operating voltage for a first time interval, with or without an additional higher pulse voltage, to produce a corona discharge, and to operate the corona discharge point () at a cleaning voltage greater than the operating voltage for a second time interval subsequent to the first time interval to produce a corona discharge. The effectiveness of the corona discharge point () can be monitored by, for instance, measuring a voltage necessary to produce a corona discharge at the corona discharge point (), measuring a current produced at the corona discharge point () from a corona discharge, and so forth.
