NMR Comparison

The CIF offers four open-access solution NMR spectrometers, and one cryoprobe-equipped spectrometer that is available for special projects. Below is a comparison of the currently available sensitivity and lineshape values for each spectrometer. Other considerations when choosing a spectrometer include available nuclei, available pulse sequences, requirements for 19F or 1H decoupling, and variable temperature limits. This page is only meant to be a guide in selecting in an instrument. Don't hesitate to ask if you still have questions about selecting the best spectrometer for your project.
