Solid-State NMR Spectroscopy | Agilent, V500 MHz DD2 WB

Location:  ECRC, Egerlandstraße 3, 91058 Erlangen, Room T00.55

The Varian 500 MHz DD2 wide-bore NMR spectrometer enables solid-state NMR spectroscopy under magic angle spinning with spin rates of up to 35 kHz. Direct excitation experiments, cross polarization, homo- and heteronuclear correlation experiments and techniques adapted to quadrupolar nuclei are possible on a wide range of materials. Sample temperatures down to -30°C are possible. 129Xe NMR spectroscopy is available for the determination of pore properties and pore connectivity in micro- and mesoporous materials. A unique in situ flow probe enables the acquisition of MAS-NMR spectra of materials at temperatures up to 250°C and in a stream of non-toxic, non-corrosive gases.
