The GG500 is located in Bagley 37, as one of the walk-on low field NMR instruments in the facility. The Avance III console is paired with an Oxford 500 superconducting magnet.
You can check the sample queue status remotely. Please pick up your daytime samples within 30 minutes of experiment completion and your nighttime queued samples by 10am the following day. Please bring no more than six (6) total samples to run at a time.
The instrument runs in automation five days a week (Friday 10am through Wednesday 10am), and on block reservations for the other two (Wednesday 10am through Friday 10am). No reservations are needed while in automation.
