Bruker AV III 600 MHz (AV600) installed in 2007:

Bruker AV III 600 MHz (AV600)

  • Higher field dispersion and highest sensitivity for polymers, carbohydrates, and natural products NMR projects or very dilute samples
  • Four RF transmitters, configured for nuclei from O-17 to H-1
  • Broad band probe with H-1 decoupling with autotune
  • Inverse probe H-1 (& F-19) with BB decoupling
  • Selective Shape pulse excitation (selective NOE, ROE) at higher field dispersion
  • Best for H-1 2D NMR or dynamic (DOSY) and kinetic projects
  • Typical application for H-1– C-13 2D (HSQC, HMBC, and TOSY-HSQC)
  • Autosampler for loading 24 samples maximum
  • Protocols: H-1 NMR at AV600C-13 NMR at AV600COSY NMR at AV600HSQC or HMBC at AV600qNMR at AV600DOSY setup at AV600DOSY at AV600

 

 

Bruker AV NEO solid-state 500 MHz (SS500) installed in 2019 (supported by NSF-MRI grant: 1726058)

Bruker AV NEO solid-state 500 MHz (SS500)

  • one 3.2 mm magic angle spinning (MAS) double resonance N-P/F-H probe: one channel is for 1H and 19F, another channel is for X nuclei (tuning frequency is from 15N to 31P). Most common nuclei can be studied: 19F, 31P, 7Li, 119/117Sn, 11B, 23Na, 27Al, 13C, 195Pt, 29Si, 77Se, 199Hg, etc. The most common experiments are mainly cross-polarization(CP) or one pulse direction observation. The unique feature of this probe can run 19F-X nuclei CP experiments additional to H-X nuclei CP experiments
  • one 3.2 mm MAS triple resonance CNH probe: one channel is for H, one channel is for 13C and one channel for 15N. The probe can run triple resonance experiments applied for biological samples
  • Both probes have variable temperature capabilities and spinning rate up to 24 kHz
  • Useful solid-state NMR information
  • Applications: SSNMR flyer & Publications employed the instrument

Bruker AV III HD NanoBay 400 MHz (AM400) installed in 2019

  • BBFO probe with Z-gradient
  • Good for H-1 2D NMR (COSY) or dynamic (DOSY) and kinetic projects
  • Typical application for C-13 DEPT and H-1/C-13 2D (HSQC and HMBC)
  • Typical X-nuclei (C-13, Si-29, P-31, Pt, Pb, Na, Cs, F-19)
  • Selective Shape pulse excitation (selective NOE, ROE)
  • Variable temperature capability
  • Protocols: Protocol for 1H NMR at AM400.pdf & Protocol for 13C NMR at AM400.pdf
