Analysis of Dissolved Methane, Ethane, and Ethylene in Ground .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 solvent- contaminated aquifer. A simple procedure is described for the collection and subsequent analysis of ground water samples for.analysis ethylene sampling,ETHYLENE GLYCOL SAMPLING | SGS GalsonETHYLENE GLYCOL SAMPLING. Ethylene glycol is a poisonous, hygroscopic liquid that is best known as an antifreeze component, but is also used in hydraulic brake fluids, and among other things, as a solvent in paint and plastic formulations. NIOSH Method 5523 is used for the collection and analysis of this compound.
