MetExpert: Portable X-Ray Fluorescence Analyzer
MetExpert: Portable X-Ray Fluorescence Analyzer

The MetExpert XRFA provides measurements of mass fraction of chemical elements in stainless, chromium and other steels, aluminum, magnesium, copper and other alloys and their products. The device can measure all chemical elements from sodium (Z=11) to americium (Z=95) in liquid, solid or powdery substances.

The analyzer has been used by military, police, customs, production and research organ-izations for materials identification and quality control, forensics, environmental monitoring (identification of toxic elements and chemical in liquids and soils) and other purposes.

Main Advantages

  • Identification of all chemical elements from sodium to americium in the base set
  • The accuracy in determining of the mass concentration of elements that is not accessible for most available handheld XRFA
  • Significantly higher reliability, stability and durability of the X-ray machine through the use of schemes with a massive anode
  • Best performance in the analysis of the full range of elements in all types of materials without replaceable filters
