MESA-7220基于能量色散X射线荧光（EDXRF）技术上的进展。它利用已获的衍射光学技术，对石油和其它液体中的低原子数元素，特别是硫 和氯，进行性能*的分析。对于要在分析硫、氯或其它元素时获得极低噪音背景，以得到检出限的用户来说，这是一种非常关键有效的方法。

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
