Анализатор MESA-7220

The MESA-7220 is based on the latest advances in Energy Dispersive X-ray Fluorescence (EDXRF) technology. It features patented diffractive optics technology 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 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

Easy

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

Clean

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

The MESA 7220 features a unique, patented design with a close-coupled, doubly curved HOPG X-ray optic. It simultaneously polarizes, focuses, and mono-chromates the X-ray beam. This yields the ideal X-ray source for measuring S, Cl and lower atomic number elements. This technique creates an environment with ultralow background similar to other optics-based X-ray analyzers, but retains the EDXRF benefit of allowing for simultaneous analysis of multiple elements.

Product Specifications

X-Ray Tube

Air-cooled, Ag anode x-ray tube; 0-12.5 kV; 0-2 mA

Monochromator

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.
