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

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
