Services

Service activities at the National Biomedical EPR Center are diverse in nature and include

  • Provision of engineering drawings, advice, and, in some cases, hardware;
  • Assistance with construction of EPR and sample-handling equipment;
  • Carrying out of HFSS simulations to assist in resonator design;
  • Provision of novel spin traps and synthetic methodology;
  • Recording and analysis of EPR spectra at 1–35 GHz;
  • Provision of advice regarding commissioning, testing, and maintaining of cryogenic equipment;
  • Matrix diagonalization computer simulations; and
  • Performance of rapid-freeze quench spectrokinetic experiments.

These activities involve the entire complement of faculty and staff at the EPR Center and often graduate students.

To apply for EPR Center services, email EPRCenter@mcw.edu or contact the faculty member with whom you previously worked. For general advice concerning EPR spectroscopy, email EPRCenter@mcw.edu or contact any faculty or staff member.

Policies

  • Collaborator Policy

EPR Center collaborators are requested to include the collaborating faculty member as an author on any publications that wholly or in part involve work carried out at the EPR Center. Any such publications should cite the Center grant number (NIH grant EB001980) and, if appropriate, the DEER instrumentation grants (NIH grants RR022422 and OD011937).  In addition, authors should demonstrate compliance with the NIH Public Access policy by securing a PMCID number for each paper citing the Center’s support. Please email EPRCenter@mcw.edu with any questions.

  • Visitor/User Policy

EPR Center collaborators are requested to include the collaborating faculty member as an author on any publications that wholly or in part involve work carried out at the EPR Center. Any such publications should cite the Center grant number (NIH grant EB001980) and, if appropriate, the DEER instrumentation grants (NIH grants RR022422 and OD011937).  In addition, authors should demonstrate compliance with the NIH Public Access policy by securing a PMCID number for each paper citing the Center’s support. Please email EPRCenter@mcw.edu with questions.

Training

Learn about the training opportunities provided by the EPR Center.

EPR Spectrometer Availability

EPR spectrometers are available to experienced spectroscopists for studies that do no require professional staff assistance. A list of available spectrometers is provided on the EPR Spectrometers page.

Contact the faculty member with whom you previously worked or email EPRCenter@mcw.edu for EPR spectrometer availability.

EPR Spectra from Samples

EPR spectra from samples submitted by mail will be obtained if the study is routine. If the study is not routine, a visit to the EPR Center is more appropriate. 

Contact the faculty member with whom you previously worked or email EPRCenter@mcw.edu.

Engineering Assistance

The EPR Center provides assistance in creating various pieces of specialized EPR equipment; this includes advice and mechanical drawings (in many cases) such as:

  • Numerous loop-gap resonators or cavity resonators as described in papers by members of the EPR Center
  • A holder for TPX capillaries in an Eppendorf centrifuge tube

Center engineers have extensive knowledge of Varian EPR spectrometers. They may be able to help individuals locate parts.

The very well-equipped microwave laboratory of the EPR Center is open to qualified users. Dr. Richard R. Mett has extensive experience in finite-element modeling of electromagnetic field in resonators.

Contact chief engineer Joseph J. Ratke or email EPRCenter@mcw.edu​ with questions.
