Electron paramagnetic resonance (EPR) spectrometer is a scientific instrument used to study materials with unpaired electrons, such as free radicals, transition metal ions, and material defects. This technique is also known as electron spin resonance (ESR) spectroscopy.
The electron paramagnetic resonance spectrometer works by measuring the absorption of microwave radiation by paramagnetic substances, including materials with unpaired electrons, such as free radicals and transition metal ions. Here’s a high-level overview of how an EPR spectrometer works:
The sample containing paramagnetic species is typically placed in a small tube or cavity within the spectrometer.
The sample is then placed in a strong, static magnetic field, which causes the unpaired electrons in the sample to align with the field.
The spectrometer emits microwave radiation at a specific frequency, typically 1-100 GHz.
The resulting EPR spectrum, which displays the absorption of microwave radiation as a function of the applied magnetic field, provides information about the nature of the unpaired electrons in the sample. This can include details about the number of unpaired electrons, their environment, and their interactions with neighboring atoms or molecules.
When the frequency of the microwave radiation matches the resonance frequency of the unpaired electrons in the sample, they undergo a transition to a higher energy state. This results in the absorption of the microwave radiation.
The spectrometer detects the absorbed microwave radiation, typically by measuring the reflected or transmitted microwave power changes.

Tabletop EPR (Electron Paramagnetic Resonance) spectrometers offer several advantages, making them valuable for various research and analytical applications. Some of the benefits of tabletop EPR spectrometers include:
- Portability: Tabletop EPR spectrometers are designed to be compact and portable, allowing for easy transportation between different locations or laboratories. This portability can be particularly beneficial for fieldwork or on-site measurements.
- Ease of use: Tabletop ESR spectrometers are often designed with user-friendly interfaces and streamlined operation, making them accessible to a wide range of researchers and technicians. This can reduce the learning curve and training time required to operate the instrument effectively.
- Cost-effectiveness: Compared to larger, more complex EPR spectrometers, tabletop models typically have lower acquisition and maintenance costs. This can make them a more accessible option for research groups or laboratories with budget constraints.
- Quick setup and measurement: Tabletop ESR spectrometers are designed for rapid setup and measurement, allowing researchers to perform experiments and efficiently obtain results.
- Versatility: These instruments can be used for various applications, including chemical analysis, material characterization, and biochemical studies, providing valuable insights into the properties and behavior of paramagnetic substances.
Electron paramagnetic resonance (EPR) spectrometers, also known as electron spin resonance (ESR) spectrometers, can be used in various scientific and research settings to analyze and study paramagnetic substances. Here are some typical applications and places where EPR spectrometers are used:

ESR (Electron Spin Resonance) and EPR (Electron Paramagnetic Resonance) spectroscopy are fundamentally the same technique with different names. This method is for detection the absorption of electromagnetic radiation by paramagnetic species.
Magnetic moments due to electrons are associated with the presence of spin or orbital angular momentum, or a combination of both. The overwhelming part of the magnetic moment is due to spin, and the orbital angular momentum of the electron makes only a small contribution, therefore the scientific community often uses the term “electron spin resonance” to reflect the influence of only the electron spin moment on the absorption of electromagnetic radiation. The term “electron paramagnetic resonance” was proposed as a term that takes into account the contribution of both the orbital and spin momentum of the electron. Therefore, both of these terms are widely used in the scientific literature and refer to the same test method.
In nature, a wide range of combinations of operating frequencies and magnetic fields is possible to obtain an EPR resonance. But in reality, everything depends on the current needs of the scientific and industrial communities, which in most cases are fully covered by the capabilities of electron paramagnetic resonance spectrometers operating at a frequency close to 9.5 GHz.
The operating frequency of the EPR spectrometer Spinscan X produced by LINEV Systems belongs to the X-band and is 9.2-9.55 GHz.
The following operating frequencies of EPR spectroscopy are also known: L band (1 GHz), S band (3 GHz), C band (4 GHz), X band (10 GHz), P band (15 GHz), K band (24 GHz), Q band (35 GHz), U band (50 GHz), V band (65 GHz), E band (75 GHz), W band (95 GHz), F band (111 GHz), D band (140 GHz).
