A second spectometer in the Ohio Advance EPR Lab (OAEPRL) at Miami makes the university one of only handful with two.

Miami University received two grant awards, totaling nearly $1.1 million, in the 2017 round of competition for the National Science Foundation’s Major Research Instrumentation (MRI) program. The national rate of success for proposals submitted to the program is only 20 percent.
“Given how competitive the MRI program is, it’s unusual that any institution would receive two awards in a single year,” said Jim Oris, Miami’s associate provost for research and scholarship. “It’s certainly a first at Miami.”
The National Science Foundation awards will support Miami’s acquisition of a pulsed electron paramagnetic resonance (EPR) spectrometer and a fluorescence activated cell sorting (FACS) system. The pulsed EPR spectrometer will be housed in the Ohio Advanced EPR Lab. The FACS system will be housed in the Center for Bioinformatics and Functional Genomics.
Pulsed EPR spectrometer enhances world-class facility
With the addition of the new spectrometer, the Ohio Advanced EPR Lab (OAEPRL) located at Miami will become one of just a handful of facilities in the world to have multiple pulsed EPR spectrometers, according to Gary Lorigan, professor of chemistry and biochemistry and principal investigator on the MRI proposal.
“There aren’t many EPR facilities in the world that have these powerful capabilities,” said Lorigan. “We already have a world-class facility here at Miami. Having a second instrument really puts us over the top.”
Spectrometers allow researchers to infer physical characteristics of matter based on the way it interacts with light or other radiative energy. An EPR spectrometer characterizes the way unpaired electrons in certain molecules or atoms spin when subjected to a magnetic field.
Pulsed EPR is used to assess certain characteristics that can’t be determined with EPR …
