REFLECTRON RFT10




REFLECTRON RFT10 Goettingen-Abel1 spectrometers

Our standard model RFT10 time-of-flight mass spectrometer is an extremely versatile instrument which is used in many different areas of research. The analyzed ions can originate from almost any ionisation process:
  • electron impact ionization of gas phase species
  • laser ionisation, VUV ionisation,
  • laser desorption and ablation from solid and liquid surfaces and small particles (aerosols, soot)
  • sputtering of surfaces (SIMS)
Features:
  • compact angled reflectron geometry
  • two-stage ion mirror
  • large two-stage channelplate detector (40 mm diameter) for high sensitivity
  • time resolution T/deltaT up to 10 000 (mass 130)
  • electron impact ionisation with magnetically guided electron beam, sweep rate up to 50 kHz
  • MS-Windows based software package for menu-driven spectrometer operation (electron impact ionisation)
  • UHV-compatible setup, (O-ring sealed flanges on request)
  • size allows use in mobile systems for environmental analysis
Geometrical Data
  • overall length 600 to 900 mm
  • (folded) field-free drift space 600 to 1200 mm long
  • connection flange CF150 (8"CF o.d.) or CF100 (6"CF o.d.)
  • flight tube with pump flange CF100 (6 "CF o.d.) and pressure gauge flange CF40 ( 2.75"CF o.d.)
  • distance connection flange - ionisation zone from 100 to 300 mm
Options:
  • mass analysis of negative ions
  • up to 20 kV postacceleration for efficient heavy particle detection with masses > 100 000 amu
  • detector with extended dynamic range to avoid detector saturation by intense mass peaks or high sweep rate
  • three-stage mcp detector for low-signal mesurements
  • additional detector behind the ion mirror
  • additional detector in front of the ion mirror, mounted on manipulator
  • parallel-wire ion gate to remove unwanted ionic species from the extracted ion beam, located in the Wiley-McLaren time focus of the two-stage ion source
Ion sources available:
for electron impact ionisation, laser ionisation, laser desorption and laser ablation, aerosol spectroscopy
