Micro-GC Agilent 490 NGA


Agilent Technologies

The 490 Micro GC can be equipped with one to four independent column channels.


The Agilent 490 Micro GC based Natural Gas Analyzers are equipped with multiple column channels; each channel includes a micro-machined capillary column and thermal conductivity detector, enabling very fast analysis times (typically less than 75 seconds). The Agilent 490 Micro GC Natural Gas Analyzers are shipped as a total solution; factory tuned for optimal separation and come with a complete analytical method, a user manual and a check-out sample. Moreover, easy-to-use software is available for the calculation of all required physical properties, such as heating value and Wobbe index, conform international standards including ASTM, GPA and ISO.


  • Very small, portable Micro GC can be operated in remote environments with complete operational simplicity, does not require a high degree of operator skill.
  • Turnkey configuration, the NGA arrives ready-to-go with proven Micro GC hardware and software, pre-loaded with analysis methods and documentation to ensure compliance with standard methods to determine the heating value of natural gases and related streams.
  • Fast analysis of NGA analytes with typical total analysis cycle time of 75 seconds.
  • Small system volume with micro-machined injector and TCD provides optimum analysis for sample streams with low sample component concentration.
  • Flexibility to analyze natural gas, liquefied petroleum gas or natural gas liquids (NGL) by use of specialized sample conditioners to ensure sample integrity for the measurements of the composition of LPG or NGL streams. Determine other components of interest, e.g. sulfur compounds, to ensure suitability for use in downstream processes.
  • Single vendor solution with all hardware, software, columns application optimization, documentation, installation and support services are all supplied by Agilent.
