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.

Key Features

  • Simultaneous element analysis

 

  • One calibration – for multiple petroleum matrices over a wide dynamic range

 

  • Dynamic Analysis Range: Sulfur: 0.7 mg/kg – 10.0 wt%   Chlorine: 0.6 mg/kg – 10.0 wt%

 

  • Various sample types including liquids, solids, pastes, powders, films and pellets

 

  • No purge or combustion gases required

 

  • Correction for Oxygen interference that can affect Sulfur results significantly in other analyzers

 

  • User defined measurement times (90 - 600 seconds)

 

  • Single digit ppm repeatability achieved on low level samples

  • Multiple Calibration Curve capability with easy storage and retrieval for matrix matching
