Natural gas is traded as a bulk commodity with prices based on energy content. Here the Agilent 490 Micro GC based Natural Gas Analyzers play a significant role. These 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.
