Analysis of Dissolved Methane, Ethane, and Ethylene in Ground Water by a Standard Gas Chromatographic Technique
Journal of Chromatographic Science
The measurement of dissolved gases such as methane, ethane, and ethylene in ground water is important in determining whether intrinsic bioremediation is occurring in a fuel-or solventcontaminated aquifer. A simple procedure is described for the collection and subsequent analysis of ground water samples for these analytes. A helium headspace is generated above a waterfilled bottle. Gases that are dissolved in the water partition between the gas and liquid phases and equilibrate rapidly. Andoi:10.1093/chromsci/36.5.253 pmid:9599433 fatcat:q66k6po6kvcqho5sjthorciwra
