BRUKER WB 500
BRUKER WB 500
in operation since June 2016
This spectrometer is mainly used in solid-state mode. If required, it can be converted to high resolution.
Sample head: PA TBO 500 W2/S4 BB H&F/P-D-05 Z
Triple equipment: ¹H and ¹⁹F on one coil
X-coil
Additional ³¹P-channel
¹H and ¹⁹F are on one coil:
→ Hetero-cores (X) can be measured ¹H-decoupled OR ¹⁹F-decoupled.
→ ¹H hetero-core 2D measurements are possible. (e.g. ¹H¹³C HMQC)
→ ¹⁹F Hetero-core 2D measurements are possible. (e.g. ¹⁹F¹³C HMQC)
→ ¹⁹F can NOT be measured ¹H-decoupled.
→ ¹H can NOT be measured ¹⁹F-decoupled.
This sample head has an additional phosphorus channel (triple equipment):
→ Hetero nuclei (X) can be measured with ³¹P decoupled in addition to ¹H OR ¹⁹F.
→ ³¹P hetero-core 2D measurements are possible (e.g. ³¹P¹³C HMQC) with or without further ¹H OR
¹⁹F decoupling (e.g. ³¹P¹³C{¹⁹F} HMQC)
Temperature experiments are possible from -40°C to +150°C. Care must be taken to select a suitable solvent.
For temperature measurements and experiments that are not measured in the automatic system, please make an appointment.
