Custom-Specific Time-of-Flight Spectrometers

MALDI Reflectron Spectrometer for Use with Cryo Detector

• Reflectron with two ion reflectors for use with superconducting cryo detector
• MALDI ion source
  
• (folded) fieldfree drift space with overall length > 4000 mm
• cryo detector sees only cold surfaces, second ion mirrors is liquid nitrogen cooled
• additional mcp detector, mounted on manipulator, can be inserted into time focus between the ion mirrors
  

Linear TOF Spectrometer for Molecular Beam Studies

• linear TOF spectrometer with ion source according to Wiley-McLaren
• detection of collision products of  two molecular beams which cross under variable angle inside the ion source and are ionised by laser
• ion source with open design to avoid scattering of molecules

Linear TOF Spectrometer for Aerosol Studies

• linear TOF spectrometer with ion source according to Wiley-McLaren
• bipolar setup 
  
• ion source optimised for aerosol studies

• reflectron with 5-grid ion reflector for quantitative ion yield measurements using lasers of extremely high intensity
  
• additional double grid structure within a two-stage ion mirror allows to measure the energy of the extracted ions with a resolution < 1%, corresponding to a spatial resolution in the ionisation zone < 2µm i.e. it is possible to measure the local ion yield inside the laser focus
  
• 8 kV postacceleration for efficient heavy particle detection
  

• linear tof spectrometer, tof axis orthogonal to direction of desorbing molecules ("orthogonal tof")
  
• detection of ions produced directly in the desorption process or alternatively of post-ionised desorbed neutrals (electron impact or laser ionisation)
• 16 kV postacceleration for efficient heavy particle detection
