ESR 200 Plus
X-band CW-ESR Spectrometer ESR200-Plus
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR)
spectroscopy is a method for studying materials paramagnetic species. ESR
spectroscopy is particularly useful for studying metal complexes or organic radicals.
ESR200-Plus is designed for CW-ESR applications. It is a powerful analytical tool for
routine ESR research. ESR200-Plus has excellent sensitivity performance due to the
use of a low-noise microwave source and high-Q resonator. It is also suitable for
quantitative ESR research, such as ESR(EPR) dating and
ESR tooth dosimetry research. It features several 2D
operation modes where the 2nd axis can be microwave
power, time, temperature, and goniometer angle.
