HR-NMR Technical Characteristics 

Varian V600 MHz

This spectrometer was installed in July 2007 and has the following features:

  • 2 RF Channels
  • Z-axis Pulse Field Gradient module
  • Ultrastable temperature control
  • Variable Temperature capabilities (from -80 to 130 oC)

 

  • 1 H( 15N- 31P) PFG AutoX Indirect 600 probe
  • 4mm Nanoprobe (gHX 8 15W- 31P[ 1H] )
  • 1 H- 19F/ 15N- 31P AutoX Dual BB600 probe

 

  • Two dimensional spectra such as COSY, TOCSY, NOESY, HSQC amd HMBC to fully characterize small molecules

 

 

Varian V300 MHz

 

  • 2 RF Channels
  • Z-axis Pulse Field Gradient module
  • Auto sampler unit with 9 sample positions
  • Ultrastable temperature control
  • Variable Temperature capabilities (from 25 to 150 oC)
  • 5mm BB( 31P- 109Ag) observe 1H/ 31P decouple
  • Gradient enabled acquisition of 1H- 19F/ 13C- 31P

 

Solid-State NMR Technical Characteristics

Solid-state NMR analysis covers a wide range of applications that cannot be addressed by liquid-state experiments. In solid-state NMR samples are place in 3,2 mm diameter spinning rotors and spun at high speeds (3-15 kHz) in order to allow acquisition of NMR spectra with sufficient resolution to allow chemical determinations to be made.

 

Varian V400 MHz Solid-State NMR

 

  • 2 RF Channels
  • Magic-angle spinning (MAS)
  • Cross-Polarization Magic angle spinning (CP-MAS)
  • Fast MAS rates - up to 15 kHz.
  • Ultrastable temperature control
  • Variable Temperature capabilities (from 50 to 100 oC)
  • 3,2mm Double Resonance HX-MAS probe

 

Other than routine nuclei (13C, 31P) are done upon request and discussion.
