XRF analyzer ElvaX is a desktop energy-dispersive X-ray fluorescence EDXRF analyzer|spectrometer which does not require liquid nitrogen cooling for storage and use. ElvaX EDXRF analyzer|spectrometer is used for quantitative and qualitative elemental analysis of metal alloys, liquids, food and biological samples, powder assays, as well as samples deposited on surfaces or filters, in the element range from Cl (Z=17) to U (Z=92) in a wide range of element concentrations. The accuracy of determining concentrations is better than 0.3% for metal alloys. XRF analyzers detecting limit is better than 1 ppm for most elements in light matrix.
