Abstract
1,035,495. Mass spectrometers. SIEMENSSCHUCKERTWERKE A.G. Feb. 4, 1963, No. 4541/63. Heading H1D. In a high-frequency mass spectrometer such as described in Specification 773,689 in which the ions are separated in dependence upon their specific charge-mass ratios by being caused to follow stable or unstable paths in a timeperiodic electric hyperbolic field, the ions after being accelerated from the ion source are decelerated when they enter the electric separating field in order to increase the resolving power attainable. Possible biasing field distributions are shown in the Figure where # 10 is the potential of the region of ion formation relative to earth, # Eb the potential of the ion injection diaphragm or possibly tube 4 and # #r the mean potential of the separating electrodes 5. In addition, especially with an electron impact type of ion source, the casing of the ionization chamber 1 may be earthed. Further alternating voltages of small amplitude may be superimposed on the separating field.
