Natural Gas Analyzer
NGA Analysis System


Natural Gas Analyzer

Shimadzu natural gas analyzer (NGA Analysis System) provides a highly flexible GC analysis platform to obtain comprehensive characterization and quantitative information, including hydrocarbon group types of oxygenates and carbon numbers. The methods for determining the chemical composition of natural gases, such as the analysis system and similar gaseous mixtures within the composition range, are shown in the table below. Excellent functions, such as the Digital Flow Controller, have been adopted and the reliability and accuracy improved.

System Lineup

Shimadzu is offering 6 standard GC systems for Natural Gas analysis according to the target compound and standard method, such as ASTM, GPA.

NGA

  • Three 10-port valves, 2 TCDs and three packed main columns are used. (Compliance with ASTM-D1945, ASTM-D3588 and GPA-2261 )

  • Approximate analysis time is 17 min.



Fast NGA

  • Capillary columns are adopted to reduce the analysis time without sacrificing separation performance.

  • 3 or 4 10-port valves are used.

  • Two TCDs (FNGA1) and one FID are used.

  • Approximate analysis time is 10 minutes.


Dual TCD + Single FID

Dual TCD + Single FID

Extended NGA
  • ENGA system uses one GC oven (single oven) with Rtx-1 capillary column for C3 to C13.
  • Split/Splitless injector is installed to split the sample and to inject the liquid standard sample.
  • Two TCDs and one FID are used.
  • A system with two GC ovens (dual oven) for extended fast NGA is also available for more flexible separation of hydrocarbons.
