Abstract
An ionization sensor includes a polarizing electrode, a signal electrode, a first dielectric layer separating the signal electrode from the polarizing electrode and a heating element configured to heat the polarizing electrode and/or the signal electrode. A method for ionization sensing includes providing a detection cell and, through a window, illuminating the detection cell with ultraviolet light while heating the detection cell, the window, or both.
