SuperQ-FT

Expand for state-of-the-art multi-frequency experiments

Multi-frequency EPR is commonly understood in terms of its relation to CW-EPR spectroscopy. Bruker’s commercial Multi-frequency/Multi-resonance EPR covers both CW-EPR and FT-EPR as well as Pulsed ENDOR and Pulsed ELDOR at a multitude of microwave frequencies.

Thanks to the ELEXSYS platform design and the advantageous intermediate frequency (IF) concept, every ELEXSYS spectrometer can be expanded for state-of-the-art multi-frequency experiments; now and in the future.

One building block, introduced in 2002, is called SuperQ-FT, a Pulsed EPR microwave bridge operating at Q-band (34 GHz). Moreover, multi-frequency Pulsed ENDOR and Pulsed ELDOR are offered as upgrade accessories to the ELEXSYS E580 and E680 lines. Furthermore, multi-frequency Pulsed ELDOR can be exploited to gather information complementary to that obtained with Pulsed ENDOR.

The perfect match to the SuperQ-FT microwave bridge is the dedicated Q-Band resonator EN 5107D2 with premium pulse EPR and ENDOR capabilities.
