EPR Imaging

X-band EPR Imaging is a powerful technique combining sub-mm spatial resolution and the specificity of EPR.  To help exploit these features, Bruker Biospin has developed the high power X-band gradients as an accessory to the ELEXSYS E-500.

EPR imaging is utilized in several research areas where the high sensitivity available at X-band is exploited to obtain high spatial resolution EPR Images.  In materials research endogenous free-radicals are monitored during material treatment.  In the biomedical field, EPR images are used in dermatology, cardiology, and cellular biology.  Critical in each of these fields is achieving the highest spatial resolution possible.

Features

• 2D Gradients in z and y directions
• 200 G / cm gradient strength
• Water cooled
• Mounts on 10'' magnet
• 25 mm air gap
• Compatible with N₂ and He variable temperature systems

The decreased air gap available with the X-band high power gradient coils necessitates a slim design resonator: the ER 4108 TMHS. This specially designed resonator fits the narrow air gap available while maintaining a high sensitivity. 

Features

• 9.8 GHz empty resonance
• 15 G maximum modulation amplitude
• 23 mm width in B₀ direction
• Compatible with N₂ and He variable temperature systems
• Optical window for sample irradiation
