Model 6400TSG Sulfur Analysis System

SKU: 6400TSG

The 6400TSG series utilizes our field-proven ultraviolet (UV) fluorescence technology to continuously monitor the total sulfur content found in process gas and liquid feeds. UV-Fluorescence is a non-consuming method of detection, eliminating the hassles associated with replacing tape cartridges, and enables detection as low as 10 ppb, depending on application, with stable, reproducible results.

  • Continuous analysis of total sulfur content, under gas-phase conditions, using the FCCM technology providing immediate, real-time TS readings for enhanced process control
  • Superior flow and temperature control of liquid-phase samples via the QTCM Pyrolysis Technology ensuring high reliability and repeatability
  • Excellent linearity for both gas and liquid phase conditions
  • Wide range of analyzer diagnostic capabilities to continuously provide plant operators with system status conditions
  • Sulfinert treated wetted parts to ensure trace levels of sulfur compounds are not absorbed into the pores of the tubing. Ensures accurate and quick response to process changes
  • Wide dynamic detection capabilities from ppb up to % levels
  • Easy-access, dual-door (front & rear) NEMA-4/4X system enclosure
  • Multi-stream, sequencing capabilities with a single system providing reduced capital and installation costs
  • Purged cabinet solutions for hazardous area installations with ambient temperature control devices designed-in for reliable field operation
  • Ethernet connection allowing for remote control without having to defeat system purge
  • Front panel, weather-proof N4 control switches allowing for local control without having to defeat system purge
