Sindie On-Line Sulfur Analyzer

Effective Online Sulfur Analysis in Petroleum Process Streams

  1. General Details

    Sindie Online is an industrial grade process sulfur analyzer with breakthrough detection capability to monitor ultra-low sulfur in petroleum or aqueous process streams. This process analyzer presents the ultimate solution for refineries and pipeline terminals where measurement speed and reliability are essential. Powerd by MWDXRF, Sindie Online uses ASTM D7039 technology and delivers real-time, continuous analysis of total sulfur from 0.5 ppmw up to 3000 ppmw. This process analyzer is ATEX and NEC certified for hazardous area locations.


    • Refinery: hydrotreating, hydrofiner, and blending processes.
    • Pipeline terminals: interface cuts, custody transfer acceptance, and tank contamination prevention.


    • Uses ASTM D7039 technology
    • LOD: 0.5 ppmw in hydrocarbon matrices @ 300 s
    • LOD: 1.5 ppmw in aqueous streams @ 300 s
    • Dynamic range: 0.5 ppmw – 3000 ppmw
    • Most application purposes, one calibration  curve over full dynamic range
    • Obust industrial design: wall mounted or stand alone


    • Continuous, real-time analysis
    • Rapid response to sample change
    • Easy to use with intuitive touch screen interface
    • Direct measurement in ppm wt
    • Low Maintenance: no consumable liquids, gasses,  combustion, or sample conversion
    • Not sensitive to sample temperature changes
