AV 400 Solids


The Bruker Avance 400 Spectrometer features a 9.4 Tesla/400MHz wide bore magnet. Topspin 1.3 software is used for data acquisition and processing. Data can also be processed using the third party MNova software. Due to the specialized nature of solid-state NMR, samples submissions are accepted for researchers with only one or two samples. Researchers with lengthy projects requiring solid-state NMR can be trained to run experiments independently. Instrument features include:

  • 4 mm triple resonance solids probe, capable of spinning speeds up to 15 kHz. In double resonance mode, the probe can tune from 15N - 11B. In triple resonance mode, the low frequency (Y) channel can tune from 15N to 13C and the high frequency (X) channel from 13C to 31P.  Variable temperature range of -100 to +100 °C.
  • AirJet chiller for VT experiments in the -30 °C to +100 °C range.

The instrument is located in 1702 Gilman Hall.  Enquiries should be directed to Dr. Sarah Cady or Dr. Shu Xu. Phone 515-294-5975 (Hach office/NMR lab), 515-294-4057 (Gilman NMR lab).
