Console and magnet

Varian VNMRS 500 (three-channel, VT, z gradient, installed 2009) with unshielded Oxford magnet (installed 1992).

Probes

• SW (switchable): ¹H (usual) or ¹⁹F (with training), and ¹³C (standard) or ¹⁵N (with training). Good for ¹³C detection
• Inverse: ¹H and either ³¹P (usual) or ¹³C (rare), with z gradient (good for 2D, but mediocre for ³¹P direct detection and poor for ¹³C direct detection)
• Nanoprobe: for semi-solid samples that require rotation at the magic angle; ¹H only; maximum spin rate ca. 2200 Hz
• 3.2 mm Chemagnetics T3 (solids probe): up to 24 kHz MAS, ¹H/¹³C-³¹P/¹⁵N-⁷⁹Br
• 6 mm Chemagnetics T3 (solids probe): up to 9 kHz MAS, ¹H-¹⁹F/¹⁵N-³¹P

Booking rules

• Up to 18 hours at a time, bookable up to 5 days in advance
• 24 hours per person per week
• If spectrometer is unused, then you may use up to 4 hours at a time (10 hours after 8 PM) even if you have already used your 24 hours per week

Notes

• This spectrometer has a chiller and the easily accessible VT range is 0 °C – 110 °C. With liquid nitrogen, the setup can go down to –100 °C
