Varian Mercury Plus 300 MHz Spectrometer

The Varian MercuryPlus 300 MHz spectrometer is a two channel instrument with z gradient capability. Channel 1, 1H and 19F, 75 W linear amplifier. Channel 2, 15N to 31P, 125 W linear amplifier. The probe is a 1H/19F/X 5 mm ATB (Automation Triple Resonance Broadband) PFG (Pulsed Field Gradient) model with the X band normally set to 13C. This allows the operator to perform the common 13C-1H indirect detection experiments and 1H, 19F, and 13C direct observe experiments without manipulating the probe. The instrument is normally configured for room temperature operation but can be adapted to run variable temperature experiments. The probe has a range of -80C to +130C. The computer system is a networked Sun Blade 150 running VNMR 6.1C.

This instrument is a modification and upgrade of an older system. The magnet from an IBM AF-300 was modified by Oxford to increase the height of the legs and allow use of Varian parts. All parts of the system except the superconducting magnet were replaced with new Varian components in 2003. The new components and installation were purchased using University funding. The magnet and the retired IBM AF-300 components were purchased in 1986 using a NSF grant.
