OLYMPUS MESA-7220 XRF and XRD Analyzers


SKU: TEP0056 Category:


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.
X-Ray Tube
Air-cooled, Ag anode x-ray tube; 0-12.5 kV; 0-2 mA
A closely coupled, doubly curved HOPG crystal is used to reflect the Ag La excitation radiation for optimal excitation of S and Cl resulting in significantly improved analytical performance. The sample chamber is under vacuum to further enhance sensitivity.
Si Drift Detector
Stable peak positions and spectral resolution (<165 eV) up to an input count rate of 90,000 cps.
Limit of Detection.
0.5 ppm wt/wt
