Installation took place in September 2000. Location : G02, School of Chemistry and Chemical Biology Spectrometer: Varian Inova 500 Probes: 500MHz 1H /15N-31P 5mm PFG Switchable Probe designed for observation and decoupling of both high frequency(1H) and low frequency(15N-31P) nuclei,with an actively shielded single-axis Z-gradient. 500MHz 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 850:1) 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: -100°C to +150°C (probe 1);  -100°C to +130°C (probe 2) Note: The Switchable probe (probe 1) on this system is the probe of choice among our instrumentation for 13C analysis of samples with very low concentration, along with the broadband probe on cscb400.
