ELEXSYS E580, the ultimate EPR System for Life Science, Materials Science and Quantum Computing



  • FT-EPR and Electron Spin Echo techniques as the basic detectors for the EPR spectrum and electron spin relaxation times (T1 and T2)
  • ESEEM and 2D-HYSCORE to measure spin density distribution and distances through the hyperfine interaction between electron and nuclear spins
  • Pulse-ENDOR to measure hyperfine interactions and nuclear spin relaxation
  • Pulse-ELDOR and DEER to measure long range distances by electron-electron spin dipolar coupling
  • SECSY and EXSY to measure correlations and exchange rates
  • Laser triggered experiments to investigate chemical reactions and triplet states



Relaxation Time Measurements

Measurement of the electronic relaxation rates, T1 and T2, offers insights into dynamics and structure. T1 supplies information regarding molecular collisions, excited state coupling, lattice vibrations, and distances between paramagnetic centers. T2 gives a wealth of information about molecular tumbling, internal rotations, dipolar interactions and distances.



Pulse EPR has matured into a well established tool for the investigation of paramagnetic species. From the very beginning Bruker set the milestones in commercial Pulse-EPR instrumentation with the ESP 380 introduced in 1987.  The next landmark was set by the successor model ELEXSYS E 580 and the new high speed digital devices PatternJet and SpecJet. For the first time in history it was possible to average FIDs and echoes at a rate governed by spin relaxation and not hampered by hardware constraints.



Another cornerstone of the spectrometer, the probehead, has been in the focus of development over many years. The result is the legendary Flexline probehead series.
The ELEXSYS E 580 FT/CW X-Band spectrometer is also the platform for multi-frequency extensions. Based on the X-Band spectrometer, frequency conversions are available to W-Band (E 680), Q-Band (SuperQ-FT), S-Band, (SuperS-FT) and L-Band (SuperL-FT). The unique design concept allows transformation of all features of the X-Band to the additional frequency in a dual-band spectrometer.



Xepr for experiment design and data handling

Unprecedented flexibility and ease of use are the attributes of the Xepr software. Whether you are dealing with a simple echo decay or a complicated multiple-pulse 2D experiment, the graphical user interface of Xepr ensures easy instrument control, experiment definition and execution. Numerous novel processing tools, display capabilities and data representations open up new dimensions in data analysis as well.
