MESA-7220*
Measurement of Sulfur and Chlorine in Petroleum Products
The MESA-7220 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, monochromatic X-ray source. This approach is critical for a user to achieve an ultra low noise background for the best limits of detection for sulfur and chlorine. 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.
*Available in the Americas. For additional information, please contact us.
