EPR in Chemistry

Metal centers, organic and inorganic radicals involved in chemical processes can be studied by EPR in various branches of chemistry: coordination chemistry, metalloorganic compounds, electrochemistry, redox processes, kinetics involving radical intermediates, photochemistry and catalysis.
EPR in material science

EPR in Material Science and Physics

Within the areas of physics and material science there are many topics of interest. EPR can be employed to investigate polymer synthesis and degradation, paint properties, testing the purity and stability of photovoltaics, semiconductors, batteries as well as carbon nanotubes. Furthermore, information can be gained about the coordination environment of transition metals, rare-earth and actinide ions.
EPR in Life Science

EPR in Life Science

EPR is a powerful tool in the field of life sciences. EPR provides insight into the structure, function and reaction mechanisms of enzymes, membrane proteins, RNA/DNA, and for characterization/screening of DNP agents. Using spin-labeled biomacromolecules enables you to study their structure and dynamics. EPR detects and quantifies reactive oxygen and nitrogen species (ROS/RNS) including nitric oxide.

EPR in Pharma

EPR spectroscopy is a powerful tool in various areas of pharmaceutical analysis: detection and evaluation of degradation, stability and shelf-life, reaction monitoring, sterilization processes and profiling of paramagnetic impurities.
EPR in Industry

EPR in Industry

In industrial settings, a wide variety of properties of products are analyzed by EPR: oxidative stability and antioxidant capacity of foods and beverages, determination of radiation dosage, post-irradiation effects on products, polymer analysis to determine failure rates, and diamond quality.

Alanine Dosimetry System

Magnettech ESR5000 is a complete alanine-EPR dosimetry system for routine dosimetry in industrial irradiation facilities, or for use as an in-house alanine reference dosimetry system.

Highest quality measurements:
The Magnettech ESR5000 instrument provides a
stronger measurement response signal than any other
bench-top EPR spectrometer on the market today, with
higher measurement sensitivity.

Cuts measurement time in half:
The Magnettech ESR5000 EPR system reduces measurement
times in half, from 40 seconds down to 10
seconds or less.

the new EPR spectrometer uses a solid-state technology,
to provide a more rugged industrial instrument for
higher reliability and uptime > 99 %.

Accommodates a wide variety of commercially available
alanine dosimeters with specialized holders.
Remote accessibility:
IP based system allows remote operation and technical
support from anywhere in the world.
