Varian Unity Inova 300

(Located in 55 NL) A three channel, multinuclear solution and solids FT-NMR instrument. All channels have waveform generators with pulse shaping capability. Pulsed Field Gradient (PFG) capability (Z only) available, suitable for diffusion and other experiments. The console was replaced with a 1996 vintage Varian Unity Inova 500 console in 2002, with appropriate modifications for the 300 MHz frequency. The original General Electric probes for the system are still usable but require a spin stack change.

Available probes for solutions:

• 5mm Varian ¹H/X probe, X=³¹P-¹⁵N (default probe)
• 10mm GE ¹⁵N-³¹P Broandband probe
• 20mm GE ¹⁷O-⁷³Ge Broadband probe
• 10mm GE ¹⁷O{X} probe
• 20mm GE ¹⁸³W{X} probe

Available CPMAS probes for solids cover the range

• 7mm Chemagnetic ³¹P-²⁹Si probe
• 7mm Chemagnetic ²⁹Si-¹⁵N probe
• 4mm Chemagnetic ³¹P-¹⁵N probe
• 3.2mm Chemagnetic ³¹P-¹⁵N probe
• Chemagnetic ²H probe, broadline, with variable temperature range of -150°C to 200°C.

General Specifications:

• Deuterium lock and unlocked mode of operation.
• Homonuclear and heteronuclear proton decoupling.
• Variable temperature capability with a range dependent upon the probe.

Host Computer:

• Sun Ultra5
• Solaris 8
• VnmrJ 2.1B
