The HELIX SFT (Split Flight Tube) mass spectrometer is a magnetic sector mass spectrometer designed for high-precision isotope analysis of small samples of noble gases. It consists of a magnetic sector analyzer with a 35 cm 120\u00b0 extended geometry ion optic. This geometry combines excellent ion optical performance with bi-directional focusing and high dispersion.<\/p>\n

Performance Details<\/b><\/span><\/p>\n

    \n
  1. Ability to measure both helium isotopes simultaneously. No apex jump required. Result in reduced analysis time and greater productivity.<\/li>\n
  2. Abundance sensitivity: The mass contribution of 4 to mass 3 is < 1 ppb. In comparison the 5400 \/ MAP215 has a mass specification of 1 ppm of 40 at 39.<\/li>\n
  3. Volume: The internal volume of the HELIX SFT system is ~1400 cc.<\/li>\n
  4. Resolution: The low mass detector, where helium 3 is measured, has a resolution > 700, which ensures that helium 3 is completely separated from the two interferences HD and H.<\/li>\n
  5. 1010\/1011\/1012 amplifiers with 50 volt range allow most analyzes to be performed on durable Faraday detectors.<\/li>\n<\/ol>\n

    Ion Source<\/strong><\/span>
    \nThe HELIX SFT system uses a flange-mounted \u201cNier\u201d type ion source that has evolved in design over the last 30 years. This source provides excellent sensitivity while maintaining a low trapping\/total emission ratio leading to long filament life and low source temperatures. It is designed for easy removal and changing of the filament. Source self-aligns on assembly.<\/p>\n

      \n
    • Self-aligning source filament<\/span><\/li>\n
    • Maximized ion production for high sensitivity<\/span><\/li>\n
    • Simple design, easy to maintain<\/span><\/li>\n<\/ul>\n

      Electrostatic Analyzer<\/strong><\/span>
      \nThe HELIX SFT low mass collector includes a 5 cm energy 90-degree filter, which allows the system to measure immense ratios regardless of peak tailings. The specification for sensitivity is <1 ppb for adjacent masses (3 contributions out of 4) at 1 x 10-7 mbar. Note the individual partial pressures of the other \u00a0gasses <\/span> present, including Neon and Argon, must be less than 5% that of Helium.<\/p>\n","protected":false},"excerpt":{"rendered":"
