We have two dedicated solid state Bruker NMR machines, one running at 600 MHz and the other at 200 MHz. We also have access to the newly expanded Imperial College London Cross-faculty NMR Centre for solution state work.

For more information on our solid state machines, please see below.

NMR solid state machines

Bruker 600 MHz NMR

We have a 600MHz Bruker standard bore superconducting magnet operating at a field strength of 14.1T, dedicated to solid state applications. This machine is used to study mobile anisotropic systems, such as model membranes and lyotropic liquid crystals.

We have a variety of probes allowing us to study a wide range of nuclei. Sample are studied either as "powder" dispersions of aligned systems, or using Magic Angle Spinning (MAS) techniques.

We can heat to around 150°C and perform low temperature work, either using an electric chiller unit or by passing nitrogen gas through a liquid nitrogen dewer.
