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, applicability over a wide range of sample types and excellent low ppm capabilities. The MESA-7220 performance is well established, as it is compliant with ASTM and ISO International Sulfur Determination Norms:

• ASTM D7220
• ASTM D4294
• IP 532
• EN ISO 8754
• EN ISO 13032
• EN ISO 20847

Key Features:

• Simultaneous element analysis
