Ion mobility spectrometer with non-radioactive ion source |
摘要 |
An ion mobility spectrometer (IMS) is provided that has a non-radioactive electron source in an evacuated chamber that is separated from the reaction chamber of the IMS by an x-ray window. Electrons from the source impinge upon an x-ray anode, causing the emission of x-ray radiation toward the window. A current controller is provided by which currents in the electron-source chamber are monitored and controlled using a microprocessor circuit. If a maximum permissible residual gas pressure is exceeded, the electron source is automatically shut down and a gettering process is activated.
