Product Description


The MESA-7220 is based on the latest advances in Energy Dispersive X-ray Fluorescence (EDXRF) technology. It features diffractive optics for ultra high performance for low atomic elements - specifically S and Cl - in oils and other fluids. This approach is critical for a user to achieve the ultra low noise background for the best limits of detection for S, Cl, and other elements.

The MESA 7220 is a specialized, compact XRF workstation that offers superior measurement of S and Cl in petroleum-based products. MESA 7220 technology is based on the latest tube and detector technologies in Energy Dispersive X-ray Fluorescence (EDXRF) and utilizing closely coupled monochromatic, polarized EDXRF analysis techniques. It was developed specially for HORIBA Scientific Elemental Analyzers Product Line utilizing Olympus field-proven EDXRF technology that originated from on-board oil and fuel analysis specially built for the marine shipping industry.

Quick & Accurate

  • Typical test times are 3 minutes per sample for less than 50 ppm concentrations
  • Less than 2 minutes per sample for concentrations above 50 ppm
  • Detection limits for S and Cl are in the low ppm level with an upper range in the % level
  • Simultaneous multielement determination capability
  • New technology eliminates oxygen interference that can vary results significantly


  • Touchscreen graphical user interface displays all the important functions for routine operation at a glance
  • USB ports allow a supervisor to easily plug in a keyboard and mouse to handle more complex tasks


  • Unlike some methods for S and Cl, the MESA 7220 models are low maintenance and do not require furnaces, conversion gases or micro syringes
