ElvaX Plus Standard XRF System

The ElvaX Plus spectrometer from Elvatech is a desktop energy-dispersive X-ray fluorescence (EDXRF) analyzer with a broad element range from Na (Z=11) to U (Z=92). The helium purge system and the automatic primary filter changer integrated with the large area SDD detector are employed to enable effective registration of the light elements spectra.

ElvaX Plus spectrometer is employed for qualitative and quantitative examination of the elemental composition of metal alloys, powders, liquids, food, and biological samples, and also samples accumulated on surfaces or filters in a broad variety of element concentrations. The analyzer’s detecting limit is better than 1 ppm for the majority of elements in a light matrix.


The robust hardware and exclusive software algorithms allow the ElvaX Plus to provide the maximum accuracy and precision of elemental analysis for a broad variety of materials


Due to the Dynamically Adaptive Shaping (DAS) DPP created by Elvatech and integrated with the Fast SDD detector, the ElvaX Plus becomes the fastest XRF analyzer available on the market.


Due to the automatic calibration adjustment, automatic temperature and pressure correction, and digiX-50 digital X-Ray source, ElvaX Plus provides long-life reproducibility of the analysis eliminating the need for system re-calibration.


  • Extensive element detection range from Na (Z=11) to U (Z=92)
  • World’s most rapid XRF analyzer (throughput above 400 000 cps) — maximum accuracy and exceptional precision within the shortest measurement time
  • Helium purge feature enhances sensitivity to light elements (Na, Mg, Al, Si, P, S)
  • Outstanding calibration stability, compensation of ambient pressure and temperature changes
  • Low maintenance cost
  • Optional high-resolution CCD camera for exact sample positioning
  • Optional 16-position automatic sample changer improves productivity of the lab

ElvaX Plus is a straightforward and robust device to swiftly perform analytical jobs on a regular basis for the broadest range of applications.

ElvaX Plus integrates a robust analytical software toolkit with a user-friendly interface, enabling even novice operators to carry out any required measurements within minutes.
