Significance and Use | ||||||||
5.1 Extraction of organic pollutants from wastes can provide information on the susceptibility of compounds to leeching, water quality changes, or other site conditions. 5.2 Rapid heating, in combination with temperatures in excess of the atmospheric boiling point of organic solvents, reduces sample extraction times. 5.3 Small amounts of solvents (30 mL) are used resulting in reduced sample preparation cost and time. |

1. Scope | ||||||||
1.1 This practice describes the closed vessel microwave extraction of soils, sediments, sludges, and wastes for subsequent determination of solvent extractable semivolatile and nonvolatile organic compounds by such techniques as gas chromatography and gas chromatography-mass spectrometry. 1.1.1 Compounds listed in Tables 1–5 can be extracted from the preceding materials. 1.2 This test method is applicable to samples that will pass through a 10-mesh (approximately 2-mm opening) screen. 1.3 The detection limit and linear concentration range for each compound is dependent on the gas chromatograph or gas chromatograph-mass spectrometer technique employed and may be found in the manual accompanying the instrument used. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
