A Versatile Six-Inch Radius Mass Spectrometer for Isotopic Analysis of Solids, Liquids, or Gases
- New Brunswick Laboratory (NBL), New Brunswick, NJ (United States)
A six-inch radius mass spectrometer was constructed for isotopic analysis requiring a minimum of instrumentation and personnel. The instrument is a six-inch radius, 60° Concent 85% sector-shaped analyzer. Its primary intended use is for low-mass work for boron and lithium analysis, as well as for comparison studies in the isotopic measurement of uranium. The work for high- mass gas samples is limited by the small radius, although the need for a dual collection ratio gas instrument is essential for comparison purposes. The instrument is designed for the analysis of a wide variety of elements by a number of different methods with minimum change in instrument geometry and source systems. A magnet current regulator designed to regulate from 0 to 550 milliamperes is used in conjunction with an accelerating voltage supply of 5000 volts which permits the isotopic analysis in a M/e range of 300 mass units. This combination permits a wide selection of ion energies resulting in excellent peak shapes and resolutions. Special vibrating reed electrometers or electron multiplier counting-type measuring systems are designed into the instrument, along with a dual collection and ratio precision potentiometer, decade-type measuring device.
