IPC: G01N27/62
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain a stabilized output signal by an arrangement wherein the rotary pump of an evacuation means for a first vacuum chamber also serves as the auxiliary pump for the turbo molecular pump of evacuation means for second and third vacuum chambers. SOLUTION: An ion lens 4 converges plus ions in a plasma passed through a skimmer orifice 3 and a mass spectrometer 6 performs determination. Second and third vacuum chambers 22, 23 have independent evacuation means, i.e., turbo molecular pumps 8, 9. The independent turbo molecular pumps 8, 9 are supplementally evacuated by a common auxiliary evacuation means, i.e., a rotary pump 10. The rotary pump 10 is coupled through a two-way valve 11 with a first vacuum chamber 21 and also serves as an evacuation means therefor. Since a steadily operating single rotary pump 10 is employed, heat is generated steadily and a control circuit subjected to the environmental temperature can function stably and a stabilized output signal can be obtained.
