Location:  NMR Laboratory, CSCB Building. Spectrometer: Varian 600MHz System, multinuclear with gradients Probes: 600 MHz  1H(13C/X)  5mm PFG Triple Resonance . Optimised for high sensitivity 1H (S/N 1200:1) , it possesses excellent RF homogeneity and salt tolerance. High performance actively shielded z-axis gradient. Probe of choice for triple resonance experiments of chemical or biological samples. High power 2H lock for deuterium decoupling. 600 MHz 1H{15N-31P} 5mm PFG Indirect Detection Probe } designed for inverse detection experiments. These experiments show correlations between heteronuclei and protons by detecting high sensitivity protons. The probe has optimal proton sensitivity(S/N 1100:1) and capability for irradiation at frequencies within the range of 15N to 31P with  actively shielded single-axis Z-gradient. Deuterium decoupling can also be carried out. Variable Temperature Range: -20°C to +80°C (probe 1) -100°C to +130°C (probe 2)            Note:  Both sfi500 and cscb600 have FTS preconditioning units enabling experiments to be run as low as -30°C without the use of liquid nitrogen. The maximum operating temperature at present is 30°C. A dedicated supply of N2 gas would be needed for temperatures higher than 30°C; such experiments (and experiments at temperatures lower than -30°C) can be performed on the cscb400 and sunucd500 spectrometers in the meantime, due to the provision of  pure nitrogen gas (necessary for probe) from a BOC liquid nitrogen tower and a liquid nitrogen dewar for low temp work. At present, we are costing  similar provisions for the CSCB Building.
