"ElvaX " EDXRF Spectrometer

ElvaX is a desktop energy-dispersive X-ray fluorescence (EDXRF) analyzer which does not require liquid nitrogen cooling for storage and use. ElvaX is used for quantitative and qualitative analysis of the elemental composition 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. Analyzer's detecting limit is better than 1 ppm for most elements in light matrix.

The spectrometer is registered in the State registry of measurement instruments accepted for usage in Ukraine under the number 141101. Certificate of the measurement instrument type is UAMI/19712001.
