The Many Applications of EPR

From cell membranes to nano-diamonds, EPR applications spread far and wide through many fields: chemistry, material research, life science, quantum physics, and quality control.

State-of-the-art EPR Operation & Analysis Software

ESRStudio is a powerful and user friendly software for EPR measurements with some of the most modern and fluent workflow based user interfaces.

A new user can start the program, analyze, and interpret their results. More advanced users will find the necessary features and analysis tools to acquire and analyze data for their advanced scientific projects.

ESRStudio supports several file formats for import. The standard export is XML, that are structured ASCII files that can be used for processing using external applications. Import functions allow analysis of previously acquired measurements.

Key Features

  • User friendly EPR/ESR operating software available
  • User/application based customization
  • Workflow for automated spectrum evaluation
  • Automated lab report generation
  • Remote access - access your EPR/ESR spectrometer from anywhere in the world via internet


The Magnettech MSR5000 ESR/EPR spectrometer is connected to a computer via Ethernet. This allows flexible installation and convenient measurement & control arrangement using short cables.

Encrypted remote access allows the user to monitor and control the measurement process from any computer within the network, and if desired, from anywhere in the world via. internet.

This remote access also allows Bruker to access the machine (with customer’s permission) to provide online training and remote technical support.
