Sample Scheduling Procedures

Project proposals from all users are assessed for scientific merit and technical feasibility through the same review process. NMRFAM utilizes iLab for reserving instrument time. Scheduling protocols prioritize projects with high scientific impact and are designed to maximize instrument usage and access for all users to cutting-edge NMR instrumentation. For spectrometers with multiple probes or shared between solution and solid-state NMR, configurations will be set and reviewed on a monthly basis. These decisions will be based on user demand for different configurations while minimizing down time for transition and striving to limit the wait from request to spectrometer time.

More on Sample Scheduling Procedures

Spectrometer time is scheduled for the highest field and highest demand instruments first. Requests for high field NMR time must justify the need for high-field and demonstrate sample quality.

Within each spectrometer calendar, the schedule is set in the following order:

  1. Remote users traveling to NMRFAM to perform experiments so that travel plans can be accommodated. This is rare (a few times a year) due to the excellent remote data collection capabilities at NMRFAM.
  2. Service requests that were denied (despite scientific merit and feasibility) in the previous month simply due to a lack of available spectrometer time or incompatible configuration.
  3. Technology development projects that require coordinated scheduling of NMRFAM staff and spectrometer time, have confirmed need and justification for the specific spectrometer and experiment, and have demonstrated sample quality. No more than 50% of spectrometer usage, limited by staff capacity.
  4. The highest scientific priority and impact service projects for each individual instrument configuration. Experiments with long acquisition times that cannot be interrupted by maintenance scheduled first. Shorter experiments are filled in to the schedule to maximize spectrometer usage.
  5. Lower scientific priority service and collaboration projects are scheduled last.

Within tiers 4-5 (≈ 50% of spectrometer usage), every effort is made to accommodate time-sensitive requests due to unstable samples or data needed for grant proposals or publication revisions with short deadlines.
