✦ Synopsis
Analysis of trace amounts of organic compounds in water usually requires recovery into a small volume of solvent before determination by gas chromatography (GC). This may be by solvent extraction'-'
or by sorption on macroreticular resirP, polyurethane foam6, carbon', or other materials8-*o before solvent extraction. In most methods the solvent phase requires further concentration which may cause serious losses of compounds'. Thus, methods of analyses which avoid the solvent concentration step are preferable for the recovery of trace organics in water.
Described below is a rapid procedure with relatively simple equipment which gives acceptable yields for the analysis of several compounds at low levels.
