In the last decade Pulse-EPR matured to 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 to transform 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.
