MESA-7220
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.
• Simultaneous elemental analysis.
• One calibration – for multiple petroleum matrices over a wide dynamic range.
• Dynamic Analysis Range: Sulfur: 0.7 mg/kg – 10.0 wt% and 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 effect 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.
• Rugged, user serviceable Kapton Windows.
• Multiple external outputs: Printer, serial I/O, USB (2) and network (RJ-45), (2 USB ports, side and back. PS2 connects, ports for mouse and keyboard,ethernet connections.)
• Accurately measures sulfur and chlorine in the presence of moisture.
