The CIQTEK EPR200-Plus is designed for CW-EPR applications. It is a powerful analytical tool for routine EPR (ESR) studies. The EPR200-Plus has excellent sensitivity performance due to the use of a low noise microwave source and a high quality-factor (Q) resonator. It is also suitable for quantitative EPR research, such as EPR dating and EPR tooth dosimetry research. It comes with several 2D operation modes where the second axis can be microwave power, time, temperature, and goniometer angle.
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectrometer is a method to study the structure, dynamics, and spatial distribution of unpaired electronics. It can provide in-situ and non-destructive information on electron spins, orbitals, and nuclei at the microscopic scale. EPR spectrometers are particularly useful for studying metal complexes or organic radicals.
Irradiated Food Surveillance
Food irradiation technology plays an irreplaceable role in ensuring food health and safety and reducing contamination and chemical residues. In the presence of ionizing radiation, the covalent bonds of internal compounds are split and a large number of free radicals are generated. Electron paramagnetic resonance techniques can detect the long-lived free radicals produced by irradiation and thus identify irradiated foods containing cellulose, bone and icing sugar, among others.
