Organic pollutants in potable or nonpotable waters, soils, sediments, sludges, solid wastes, and other matrices must be brought into an appropriate organic solvent for their injection into the GC column. Such extraction also enables the increase of the concentration of analytes in the samples by several orders of magnitude for their detection at ppb or ppt level. Depending on the nature of the sample matrices, various extraction techniques may be effectively applied for the accurate and low-level detection of organics. These are outlined in Figure 5.1.
