This method is used for a variety of purposes. Uses include determination of nonhalogenated volatile and semivolatile organic compounds (SVOCs), gasoline range organics (GRO), diesel range organics (DRO), and as a semi-quantitative screening tool to prevent sample overload on GC/MS (gas chromatography/mass spectrometry) systems. GROs are alkanes from C6 to C10 with boiling ranges approximately 60 °C to 170°C. DROs are alkanes from C10 to C28 with boiling ranges approximately 170 °C to 430°C.
Identification of single component analytes requires a second column confirmation by GC/MS. Second column confirmation is typically not needed for petroleum hydrocarbon analysis. However, if analytical interferences are present, a second column confirmation is required.
NOTE: This method replaces SW-846 Methods 8015, 8015A, and 8015B.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
