Standard Test Method for Measurement of Dissolved Gases Methane, Ethane, Ethylene, and Propane by Static Headspace Sampling and Flame Ionization Detection (GC/FID)

Importancia y uso:

5.1 This test method covers the determination of the dissolved gases methane, ethane, ethylene, and propane in drinking, waste, and ground waters, including domestic wells; whether naturally occurring or resulting from commercial activities, dissolved gases can be hazardous both to the environment and humans. Due to increased scrutiny of dissolved gases, developing a valid method for the testing of dissolved gases in water has become more imperative. Static headspace sampling is generally applicable for sampling these compounds. However, as these compounds are extremely volatile, a closed sampling system is recommended. This test method can be used for quantitatively determining dissolved gases in ground, waste, and drinking waters.

5.2 This test method is suitable for analysis of domestic drinking water samples from residential and commercial water supply wells prior to oil and gas exploration activities to form a baseline for monitoring potential impacts during exploration; development, including hydraulic fracturing; operation; closure; and reclamation of nearby oil and gas production and injection wells.
