Abstract

938,740. Mass spectrometers. SIEMENS-SCHUCKERTWERKE A.G. March 24, 1961 [March 25, l960], No. 10972/61. Class 39 (1). The R.F. mass spectrometer described in Specification 773,689 consists of three independent structural units: (1) the tubular metal casing 11 with gas supply conduit 17 and insulated ion current collector 16, (2) the analyser system, consisting of four rods, 24, which is inserted within unit (1), and (3) the ion source 21 and a flange 19 for connecting the ion source to one end of the metal casing 11. The flange surfaces 18, 19 can be flat, cylindrical, or conical. A diaphragm 14 between the analyser system and the ion collector has a flange 14a which is secured between the metal casing 11 and a sleeve 13 which is sealed into the glass cap 12. Two diaphragms 22 are provided between the ion source and the analyser system. The rods 24 of the analyser system are secured by elastic insulating rings 25, 26, the rods being accommodated in recesses in the rings and being engaged by radial screws. In another method of mounting the rods, the rods are secured in apertured mica end rings and held by screws entering into the ends of the rods.
