Ion mobility spectrometers with a non-radioactive electron source

摘要

Ion mobility spectrometers with a swelling chamber in which there is a non-radioactive electron source is located, and a reaction chamber which, by means of a permeable for electrons and for gas impermeable partition wall of the sources chamber is separated, characterized in that the non-radioactive electron source a gas discharge at a pressure of between 10 and 1000 pascals is.
