Abstract
In atmospheric pressure chemical ionization as usually used in ion mobility spectrometry radioactive beta minus sources provide free electrons with high kinetic energy to initiate a chemical gas phase ionization of the analytes. In this paper we present a simple to manufacture miniaturized non-radioactive electron source to provide the free electrons at atmospheric pressure. Therefore, we generate free electrons by classical thermo emission from a tungsten filament in vacuum. The emitted free electrons are then accelerated towards an electron transparent 300 nm thin Si3N4-membrane through which the electrons are transferred from vacuum to atmospheric pressure. The average kinetic electron energy at atmospheric pressure is 8.6 keV.
