NGA-1 Natural Gas Analyzer

Natural gas is a widely used resource. Its monetary value is based largely on its heating value or BTU content. Gas chromatographic methods published by the Gas Processors Association (GPA methods 2261 and 2177) for the analysis of natural gas are not only used to analyze natural gas for composition but are ideal mechanisms for calculating the BTU content as well as other physical properties such as specific gravity and compressibility.

The chromatogram above show an example from our NGA-1 natural gas analyzer, which is recommended for the analysis of gases with low concentrations of heavier hydrocarbon components. With this GC system, all compounds larger than C5 are backflushed as one peak. A trace level sulfur compound analysis can be added to this GC as an option. If your samples have moderate or high levels of C6 or higher hydrocarbons, please see the Application Note on our Extended Natural Gas Analyzer.
