Reflectron time-of-flight mass spectrometer (RETOFMS) combined with vacuum chamber

  • Detected mass range: 1-5000 u for positive ions and 1-3000 u for negative ions.
  • Mass Resolution: > 800 (measured with the background gas using the provided on-board electron impact ionizer).
  • Possibility of detection: positive ions, negative ions, neutrals
  • Registration  time resolution: A time-to-digital converter with time resolution of 0.25 ns;
  • Operational conditions:
    • high vacuum;
    • ambient gases: He, O2, N2, Ar.
  • Vacuum system:
    • Ablation vacuum chamber (below 5.7´ 10-5 mbar). Size: 500 mm inner diameter and 600 mm inner height.
    • RETOFMS vacuum chamber
    • Under high vacuum conditions (below 2 ´ 10-7 mbar);
    • Under ambient gas conditions: RETOFMS chamber (below 2 ´ 10-6 mbar) when the ambient gas pressure in the plasma chamber is 0.7 mbar;
