MESA-7220
The MESA-7220 delivers the latest innovation in field measurement of S, Cl, and other elements in petroleum-based products. This analyzer is based on the latest advances in Energy Dispersive X-ray Fluorescence (EDXRF) technology. It utilizes a proprietary X-ray optical technology and produces a polarized, mono-chromatic X-ray source. This approach is critical for a user to achieve an ultra-low noise background for the best limits of detection for S, Cl and other elements. This provides excellent performance at high concentration (multiple wt. % levels), simultaneous multi-element analysis, and applicability over a wide range of sample types and excellent low ppm capabilities.
