NGC8207 Natural Gas Chromatograph

Brand: ABB Group

The NGC (Natural Gas Chromatograph) performs on-site gas analysis and heating value computation where current chromatograph technology has been either impractical or unaffordable. 

This truly “transmitter-like” GC takes up no more room on the pipeline than most multivariable transmitters.

The NGC8207 analyzes each sample utilizing established chromatographic techniques. 

The resulting information consists of mole percent values for the following:
  • “Air” (Contains N2, Ar, CO and O2 but not CO2)
  • C1, CO2, C2, C3, IC4, NC4, NeoC5, IC5, NC5, C6’s, C7+
Features
  • Designed for pipeline-quality natural gas
  • Environmental temperature
  • Four stream capability; Manual calibration required with 4 sample streams
  • Single auto calibration stream and 3 sample streams, or 2 auto calibration streams and 2 sample streams
