The NGC8209, the C9+ natural gas chromatograph performs on-site natural gas analysis and heating value computation using an extended analysis.

On-line chromatograph techniques are used to provide N2 through C6+ data while a third column train is used to separate the C6+ fraction. The NGC8209 utilizes the modular and scaleable XSeries software framework to integrate data from a third analysis train into the standard C6+ analysis of the Natural Gas. The extra chromatographic information is provided as NC6’s, NC7’s, NC8’s and C9+ to provide this “extended analysis”. Heating value (CV), Wobbe, Relative Density (SG) and other calculations are performed using the combined analysis data in a similar manner to the NGC 8206. Hydrocarbon Dew Point (HCDP) and Speed of Sound (SOS) calculations are available options.
