摘要：Looped ionization sources for ion mobility spectrometers are described. Theionization sources can be used to ionize molecules from a sample of interest in order toidentify the molecules based on the ions. In an implementation, an electrical ionizationsource includes a wire that is looped between electrical contacts. The wire is used toform a corona responsive to application of voltage between the wire and the walls of anionization chamber. The corona can form when a sufficient voltage is applied between thewire and the walls. A difference in electrical potential between the wire and a wallforming an ionization chamber, in which wire is contained, can be used to draw the ionsaway from the wire. In embodiments, the wire can be heated to reduce the voltage usedto strike the corona. The ions, subsequently, may ionize the molecules from the sampleof interest. The looped corona source can also be used in mass spectrometers (MS).
