Determination of Nanogram per Liter Concentrations of Volatile Organic Compounds in Water by Capillary Gas Chromatography and Selected Ion Monitoring Mass Spectrometry and Its Use To Define Groundwater Flow Directions in Edwards Aquifer, Texas

A method developed to measure nanogram per liter amounts of selected volatile organic compounds and the isomers of dichlorobenzene in water is described. The method uses purge-and-trap techniques on a 100 mL sample, gas chromatography with a megabore capillary column and electron impact selected ion...
