Applications

¹H, ¹⁹F, and 2D for high-throughput work; ¹³C for concentrated samples. Sometimes ³¹P (depending on probe installed).

Console: Varian Mercury (two-channel, z gradient)

Console and magnet

Varian Mercury (first installed 2002; donated to McGill 2012) with unshielded Oxford magnet (2002). 

Probes

• AutoSW (most commonly used): simultaneously tuned to ¹H, ¹⁹F, and either ¹³C or ³¹P (most commonly tuned to ¹³C). Has z gradient, so good for 2D
• AutoNUC: simultaneously tuned to ¹H, ¹⁹F, ³¹P, ¹³C. No gradient

Autosampler

100-position SMS sample changer

Usage rules

• No need to book in advance
• Sample changer is first-come, first-served
• 90 min usage permitted per sample during the day
• Longer experiments must run at night

Notes

• Teaching labs use the instrument during term, but otherwise, the instrument is usually free
• When the AutoSW probe is in and tuned to ¹³C, the HSQC is a good experiment – consider using it along with the basic ¹H for simple characterization
• The sample changer can only use 8” tubes
• Pink NMR tube caps indicate that the tube belongs to the teaching lab – do not use pink NMR tube caps unless you are in an undergraduate lab!
