The e-scan is a reliable EPR system, optimised for the best price-performance ratio. A multi-purpose version is available, as well as dedicated analysers for specific real-world applications. The Bruker e-scan is a compact benchtop EPR spectrometer. Antioxidant levels in tea, wine, coffee etc.Free radical content in solid foods (using heptane extraction).Analyse edible oils with forced oxidation assay.Measure free radical srecombination during thermal annealing.Accurate dose measurement from either alanine film or pellet.Monitor asphaltene radicals and vanadium content in crude oil.Analyse ROS and Nitric oxide/Endothelium-derived relaxing factor in physiological samples.OH, H 2O 2, ONOO−), RNS (NO, NOHb) and S-centered radicals.Directly detect free radicals (antioxidant-derived, polymer and organic).Data is acquired in a matter of seconds, with analysis providing useful information about the amount and identity of species present.Īpplications Science / Research Applications It can be used to detect unpaired electrons in solids, liquids, gases, coloured and turbid solutions and cell suspensions. They can also contribute to degradation of material properties, eg brittleness and discolouration of polymers.ĮPR is a versatile and non-destructive analytical method. These include:įree radicals and transition metals are vital to many processes, including photosynthesis, oxidation/reduction, catalysis, and polymerisation.ĮPR is relevant in a variety of fields, including medical science, biology, chemistry, physics, material science, archaeology and forensics. Most free radicals have damaging effects on their surroundings they are involved in cancer, aging, Alzheimer’s and cardiovascular diseases.

The e-scan product line from Bruker is a series of easy-to-use, benchtop EPR spectrometers that make EPR technology more accessible, with analysers developed for specific, real-world applications.īlue Scientific is the official distributor of benchtop EPR instruments from Bruker. EPR is the only method of scientific analysis that can directly and unambiguously detect free radicals. EPR (Electron Paramagnetic Resonance, also known as Electron Spin Resonance) is a spectroscopic technique which detects unpaired electrons.
