This information provides quality data, and a basis for calculating physical properties such as molecular -weight on these fractions. A system with two GC ovens dual oven for extended fast NGA is also available for more flexible separation of hydrocarbons. This test method may be abbreviated for the analysis of lean natural gases containing negligible amounts of hexanes and higher astm d, or for the determination astm d d11945 or more components, as required.
ASTM D – 14 Standard Test Method for Analysis of Natural Gas by Gas Chromatography
D – 96 Standard Test Method for Analysis of Natural Gas by Gas Chromatography 1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Ll Repeatab ility-The difference between two successive results obtained by the same operator with the same ,apparatus under constant operating conditions on identical test materials should be considered suspect if they, ,differ by more than the following a: The purity of the carrier gas may be improved.

Methane and lighter may be expressed as the difference between A2. Inject the sample be temperaturl? Separation of carbon dioxide must be sufficient so that a 0. The detector temperature shall be equal to or greater than the maximum column temperature.
Copper and copper-bearing alloys are unacceptable.
Obtain a corresponding response on a 8. By Authority of the Code of Federal Regulations: Avoid introduction ofliquids into the sample system.
Larger samples may be used to determine low-quantity components in order to increase measurement accuracy. Close the cylinder valve and allow the pressure of the sample 9. The composItion of the sample is calculated by comparing either the peak heights, or the peak areas, or both, with the corresponding values obtained with the reference standard.
Shimadzu natural gas analyzer NGA Analysis System provides a highly flexible GC analysis platform to aastm comprehensive characterization and quantitative information, including ast, group types of oxygenates and carbon numbers.
