Electron Spin Resonance Spectrometer (ESR) Model：JES-X3
Electron Spin Resonance (ESR) is a powerful analytical method to detect, analyze and determine the characteristics of unpaired electrons in a substance. It is clear that the state of electrons in a substance have a strong influence on tis characteristics and functionality, so evaluation by EST is becoming more and more important. Many types of substances, from electronic materials to catalysts, biological samples, can be studied regardless of whether they are solid, liquid, or gas. A wide range of ESR techniques are possible using suitable attachments together with the basic instrument.

Recently, it has been widely accepted that even relatively few unpaired electrons in a sample can affect the function of the material, so lower detection limits (higher sensitivity) is required of ESR measurements.The ESR spectrometer JES-X3 series has an improved a low-noise Gunn oscillator providing a 30% improvement in sensitivity compared to previous models.
- Improved sensitivity with the ultra-low noise Gunn oscillator
- Built-in microwave frequency counter
- Intuitive user interface
- Various automatic measurement modes
- 3 types of magnets to suit the application
- Zero cross-field sweep function
- Wide variety of attachments
