MESA-50 X-Ray Fluorescence Analyzer


HORIBA has been selling the XGT-WR series of EDXRF analyzers for many years, to providing screening measurements of samples containing hazardous elements such as Pb, Cd, Hg, Cr, Br, Sb, As for RoHS, ELV, and Cl for halogen free applications.

XGT systems are used daily throughout the world.  HORIBA has now developed the new MESA-50 EDXRF analyzer, based on its long experience with customer requirements and knowledge. MESA-50 provides user friendly operation and good performance. MESA-50 includes three analysis diameters, suitable for every sample, from thin cables and electronic parts to bulk samples. The combination of SDD detector and DPP changes the image of EDXRF.

HORIBA's new MESA-50 supports ecological procurement; it contributes not only to EU RoHS and ELV compliance testing, but also regulatory work for many other countries.

  • Portable, small footprint and light weight
  • Internal battery power supply

3. Simple

  • Reduce routine maintenance work (LN2 free operation)
  • No need for vacuum pumps
  • Intuitive simple measurement process for all material types

4. Smart

  • English / Japanese / Chinese user interfaces
  • Excel® data management tool

5. Safe

  • No worry about X-ray leakage

Powerful Software Tool for RoHS, ELV and Halogen-Free Applications

Enhanced software for screening samples containing harmful elements, such as lead, cadmium, chromium, mercury, bromine for RoHS, End of Life compliance, and chlorine for halogen-free As and Sb applications. MESA-50 is the perfect instrument for lab-based and field-based elemental analyses.

  • New flexible layout enabling users to prioritize what windows they want to see
  • Analyze one set of results while performing measurements on another.
  • ‘Auto Material Identification’ For RoHS and ELV measurements will ‘pre-measure’ a sample in 10 seconds. Then it will classify the sample, select a suitable measurement condition, and set parameters for each matrix. The operator does not need to make these decisions.
  • ‘Automatic Judgement and Measurement Termination’ function determines whether the sample is OK or Not Good (NG), based on the concentration of harmful elements in the sample are above or below the threshold values. MESA-50 stops automatically when that decision is reached. This shortens the measurement times and enables more efficient screening analysis.
