ElvaX Light Spectrometer is a desktop energy-dispersive X-ray fluorescence (EDXRF) analyzer with extended element range from Na (Z=11) to U (Z=92). The Helium purge system and the automatic primary filter changer are used to allow effective registration of the light elements spectra. ElvaX Light Spectrometer 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 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 EDXRF Spectrometer is registered in the State registry of measurement instruments accepted for usage in Ukraine under the number Ó1411‑01. Certificate of the measurement instrument type is UA‑MI/1‑971‑2001. Fields of application- RoHS & WEEE
