Rosemount™ 1500XA Process Gas Chromatograph
The Rosemount 1500XA process gas chromatograph combines the proven analytical components of Emerson's field-mounted gas chromatographs with the larger oven capacity of a traditional air-bath oven design.
This modular and scalable analyzer provides unmatched flexility and reliability within a single analyzer and can be configured for various process gas applications.

  • Traditional air-bath oven design for maximum application flexibility
  • Dual Ethernet communications for connection to DCS systems and maintenance wide area networks using industry standard protocols
  • New XA valves, based on the reliable design of our line of superior 6-port chromatograph diaphragm valves.
  • Oven capacity for up to eight chromatograph valves and four detectors, up to two of which can be flame detectors
  • Choice of thermal conductivity flame ionization, and flame photometric detectors
  • Thermal conductivtity detector (TCD) sensitive down to very low parts-per-million levels
  • Storage of up to 2,500 chromatograms, including sample calibration and validation streams
  • 2 clocks allow up to 2 applications with different analysis cycle times to run simultaneously
  • Optional inter-column thermal conductivity (ITC) detectors
  • Parallel chromatography to break down complex analysis into simpler analysis trains to improve cycle times and ease of use
