Gasoline Range Organic Detection and Screening Using Static Headspace

In general, Gasoline Range Organic (GRO) compounds correspond to a range of hydrocarbons from C6 to C10. These hydrocarbons have boiling points below 170°C and are often found in ground water and soils. The cause of this water or soil contamination can vary from the simple leaking underground storage tank to catastrophic such as the Gulf Oil spill. When GRO compounds are found, the site of the pollution needs to be tested in order to determine the level of the contamination. One method to determine the amount of contamination is to perform static headspace sampling in conjunction with Gas Chromatography/Mass Spectrometry analysis. This application note will explore static headspace sampling of GRO water samples using the EST Analytical LGX50.
