Solid-State NMR Spectrometer

Equipment Name: Bruker 400 MHz AVANCE NEO Spectrometer

Facility Website: https://solidstatefacility.wustl.edu

Location: 075 Whitaker Hall

Description: Nuclear Magnetic Resonance (NMR) spectroscopy is an experimental technique used widely in chemistry, materials science, and chemical and environmental engineering that utilizes a large external magnetic field and radiofrequency pulses to obtain physical and chemical information about the materials of interest. In addition to typical experiments, this instrument is uniquely equipped with a 400 MHz Bruker AVANCE NEO spectrometer and a Phoenix NMR probe capable of performing high temperature (up to 250 C) and high pressure (400 bar at 20 C, 200 bar at 250 C) NMR experiments for in-situ analysis.

Capabilities:

Our spectrometer is uniquely equipped for applications to a wide range of disciplines, including catalysis, geochemistry, materials synthesis and characterization, and membrane research activities. For a more in depth look at these topics and our specific instrumentation, please refer to our facility website. Briefly, we have two magic angle spinning (MAS) probes:

Bruker 4mm MAS Double Resonance Probe

• ¹H/¹⁹F channel, 500 W
• Broadband X (¹⁵N-³¹P) channel, 1000 W
• Maximum temperature: 150 °C
• Maximum spinning frequency: 14,000 Hz

Phoenix NMR High Pressure/Temperature MAS Double Resonance Probe

• ¹H/¹⁹F channel, 500 W
• Broadband X (¹⁵N-³¹P) channel, 1000 W
• Maximum Temperature: 250 °C
• Maximum Pressure: 400 bar at 20 °C; 200 bar at 250 °C
• Maximum Spinning Frequency: 12,000 Hz at 20 °C / atmospheric pressure; 5,000 Hz at 250 C / 200 bar
