MESA-50K X-Ray Fluorescence Analyzer


In order to meet RoHS/ELV and to analyze hazardous elements, HORIBA has offered the X-ray Fluorescence Analyzer XGT-1000WR series. Since 2002, 1000 units have been used all over the world for these applications to meet the critical needs from our customers to analyze the sample without cutting it. In 2012, an intuitive MESA-50 X-ray Fluorescence Analyser was released. It became every popular in a very short amount of time, and in 2013 a new type of MESA-50 with a big sample chamber has been added to the MESA-50 series.  It is equipped with the sophisticated LN2-free detector.  As/Sb analysis function and Multilayer Film FPM are available as options.


1. Speedy

  • Silicon Drift Detector (SDD) drastically reduces measurement times, and provides increased sensitivity, for true high throughput analysis.

2. Small

  • The MESA-50K features a large sized chamber without compromising the minimum footprint. Can be simply connected to PC via USB.

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.
