The Contract Laboratory Program (CLP) analysis methods for use at Superfund sites are designed to provide reliable data for a wide range of analytes. `Me method for determination of volatile organic compounds is a purge and trap method, a procedure which is superior for non-polar, highly water insoluble compounds. However, the purge and trap procedure is often not suitable for analytes with high water solubility, such as 1,4-dioxane. This compound is a highly useful solvent because of its ability to solvate many polymers and because of its solubility in water and in various organic solvents. Unfortunately, 1,4-dioxane is both toxic and relatively resistant to biodegradation. Therefore, there is a need for a reliable and efficient method for determination of this compound at low ppb levels. The Environmental Protection Agency (EPA) has begun to endorse microscale extraction methods as reliable alternatives to purge and trap procedures, under certain circumstances. For example, drinking water method 551 allows for the extraction and determination of halogenated solvents with high recoveries and low detection limits. Of particular interest is the fact that the extraction procedure allows for the analysis of highly water soluble volatile compounds, such as chloral hydrate, which are not purgeable. This paper will describe the development of a microscale solvent extraction (MSE) procedure for the gas chromatographic determination of 1,4-dioxane. The method is designed for laboratory or on-site use, has high recovery, and has an aqueous detection limit below 2 {mu}g/l in water.
