The instrumentation cards from Spectrum Instrumentation, a specialist in digitizers and generators, are used as key components in next-generation EPR spectrometers and have been recognized for their performance.


Spectrum announced on the 17th that its Arbitrary Waveform Generator (AWG) and digitizer have proven their capabilities as core components in the next-generation Electron Paramagnetic Resonance (EPR) spectrometer launched by U.S. startup Bridge12.

EPR, or electron spin resonance (ESR), spectroscopy is similar to nuclear magnetic resonance (NMR) spectroscopy, but studies the properties of unpaired electrons rather than nuclei such as protons.

It is used in the study of the electronic structure of metal complexes or organic radicals in the fields of chemistry, biology, materials science, and physics, but there was a problem that the EPR spectroscopy required a huge electromagnet weighing more than 1 ton, so the base had to be located in a basement.

Accordingly, a startup called 'Bridge12' located near Boston, USA, has released a next-generation EPR spectrometer that is 1/10th the size and weight, can be installed on any floor of a building, and is 50% cheaper than existing equipment.r />
The core components of this spectrometer include a spectrum measurement card consisting of an AWG that generates pulses and a digitizer that collects the return signal.

“As a startup, we were able to start from scratch and build a next-generation EPR spectrometer that is significantly more compact than existing products,” said Thorsten Maly, Vice President of Magnetic Resonance at Bridge12. “Many of our customers are university researchers who are introduced to EPR spectroscopy through collaborations, and the availability of an affordable, state-of-the-art instrument will make this methodology more accessible. Another goal is to make EPR spectroscopy accessible to more scientists by making it easier to use than existing instruments that require a separate operator.” “Bridge12’s control software is intuitive with automated features. It’s easy to set up, and you can immediately see if your experiment is working correctly, so even if you’re not an EPR spectroscopy expert, you can get the results you want.”
