Instrumentation

Bruker Elexsys 500 Spectrometer

The EPR facility was originally comprised of a Bruker ESP 300 and a Bruker EMX spectrometer.

The ESP 300 has been decommissioned and replaced with a Bruker Elexsys 500 spectrometer through generous funding from the Wellcome Trust Equipment Fund.

Publications that arise from the use of this instrument should acknowledge the ARC and the Wellcome Trust Equipment Fund.

The Elexsys 500 has a 15” magnet equipped with rapid scan coils and can be operated in X-band (8-10 GHz), Q-band (35 GHz) or L-band (1.1) GHz modes.

A Super Hi-Q cavity is currently installed for use in X-band and has been used to examine metal complexes in pharmaceutical preparations, radical reactions, polymerisation processes and thin film deposits on plastics.

EMX Spectrometer

The EMX spectrometer has an 8” magnet and operates in the X-band mode.

This instrument is used for room temperature measurements of solids and special flat cells can be used for solution work.

The EMX has been used to examine metal complexes in the solid and in solution, polymerisation processes as well as coals and clays
