Rosemount™ 700XA Process Gas Chromatograph
Designed for optimum reliability and flexibility, the Rosemount 700XA Process GC provides extended gas composition analysis with remote operation capabilities in an explosion-proof, field-mountable design.
This reduces the need for elaborate analyzer shelters or temperature control requirements. Whether it is heating value measurement, trace contaminant monitoring, or product quality and process control, the Rosemount 700XA offers the flexibility to combine measurements in a single, transmitter-style GC, reducing footprint and total cost of ownership.

Features

  • Industry's first transmitter-style gas chromatograph capable of combining the measurement of natural gas energy content, hydrogen sulfide, speciation of total sulfur compounds to trace levels, and hydrocarbon dew point (HCDP) calculations in a single-analyzer solution
  • Explosion-proof and ATEX/IECEX safety rating enables field installation without enclosure even in Class 1, Division 1 areas
  • No instrument air for purge or oven required, reducing power consumption over traditional air purged GC units
  • Secure, remote operation capabilities enable audit checks and reduce the need to attend remote locations
  • Wide dynamic measurement ranges from percent to trace-level components
  • Micro flame photometric detector (µFPD) and micro flame ionization detector (µFID) sensitive to parts-per-billion levels
  • Thermal conductivity detector (TCD) sensitive down to low parts-per-million levels
  • Reliable performance over broad ambient temperatures -20 °C to 60 °C / -4 °F to 140 °F (application-dependent)
  • Fully compatible with modern Ethernet networks and DCS communication
  • Storage of up to 2,500 chromatograms, including sample calibration and validation streams
