BENCHTOP ELECTRON PARAMAGNETIC RESONANCE SPECTROMETER (EPR)
Transition metals play a fundamental role in biological processes, catalysis, in materials science. Benchtop Electron Paramagnetic Resonance Spectrometer (EPR) LINEV SPINSCAN X is an excellent instrument for analyzing the transition metal complexes and free radicals in liquid or solid. It delivers powerful performance and extremely compact size, and low weight at minimized costs. SPINSCAN X makes it possible to observe in-situ the reactions generated by optical CW and pulsed illumination, by chemical additions, and under-sample heating and cooling.
SPINSCAN X is a valuable tool for spin trap or spin labeling techniques, for studies of the polymerization and degradation reactions, for alanine and food dosimetry. SPINSCAN X is affordable equipment for postgraduate research and education.
SPIN trapping & spin labelling
A large variety of spin traps and probes for detecting known or specific free radical species are available for studying different properties and processes in biochemical, biological, and other systems.
Benchtop EPR spectrometer SPINSCAN X with the sensitivity and resolution parameters comparable to large systems makes it possible to detect free radicals with high specificity.
You need just a small sample volume (~50-100 μL) even at nanomolar concentrations of paramagnetic species for the measurement. SPINSCAN X is a good solution for routine measurements in any laboratory.
SPINSCAN XEDU, benchtop EPR spectrometer, and its educational kit are excellent solutions for educators and students to go deep into electron paramagnetic or resonance spectroscopy (EPR or ESR) using well-established methods.
It is a suitable unit for the individual and groups of undergraduate students, postgraduates, and researchers who intended for advanced materials’ research work.
Educational Kit includes a step-by-step procedure of numerous EPR techniques and laboratory exercises.
If you will see the label Radura on the food, it indicates they have been treated with ionizing irradiation what is similar to pasteurization.
Irradiation of alimentary goods to preserve them from microorganisms and extend the shelf-life of foods is technologically advanced, secure, and low-cost. It keeps products’ natural taste and attractiveness.
This method’s advantage is the ability to process them packaged, while the products do not form radionuclides, producing free radicals. Currently, a large number of products are exposed to irradiation: meat, seafood, fruits, vegetables, cereals, spices. The dose rate depends on the product type.
Electrochemistry and EPR
SPINSCAN X and new designed disposable two-electrode electrochemical cell for in-situ electron paramagnetic resonance (EC-EPR) spectroscopy with small portable potentiostat open the gate for new analytical applications.
It is ideal for both electrochemical and simultaneous EPR measurements as it is easy to handle and mount. The electrochemical EPR experiment is running under the control of a basic software package. ERP can efficiently use this solution to study short live radicals or redox mechanisms.
Foods and drinks these days are intensive investigation subjects, and their benefits correlate with their antioxidant properties, and the stability is becoming increasingly important as its essential quality. SPINSCAN X can provide such control with EPR spin trapping technique.
EPR spectroscopy is a precise technique for studying radiation and photo-induced polymerization reactions, free radical and redox polymerization for photo mechanism, radiation, and mechanic destruction of polymers.
EPR Spectra of spin probes and spin labels are very sensitive to the polymer solution’s phase conformation. Process EPR Analyzer SPINSCAN X can monitor online the phase separation of polymer solution during its production.
The aging of the polymer materials caused by their structure and environmental conditions can be diagnosed by EPR spectroscopy. The process of degradation became clear by direct detection of the intermediary radicals and EPR Spin Trapping technique.
SPINSCAN X EPR spectrometer and variable temperature control system from -170C up to +550 C with window and UV accessories for irradiation deliver powerful capabilities for monitoring free radicals in the cavity thermal UV treatment of polymers on site.
According to ISO/ASTM, an EPR spectrometer SPINSCAN XDS meets all requirements of standard practice for alanine-EPR dosimetry systems according to ISO/ASTM considering all types of alanine dosimeters forms (pellets, films, capsules, etc1).
SPINSCAN XDS has controlling and data acquiring software to perform the validation and calibration.
The alanine dosimetry system is recommended for irradiation centers that do food irradiation, polymer modifications, medical and pharmaceutical product sterilization, and radiation damage studies in materials.
