DocumentationTraining - Rates


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). 


  • 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


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


  • 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!
