EPA-8011 方法气相色谱法测定1,2-二溴乙烷和1,2-二溴-3-氯丙烷.pdf

METHOD 8011 1,2-DIBROMOETHANE AND 1,2-DIBROMO-3-CHLOROPROPANE BY MICROEXTRACTION AND GAS CHROMATOGRAPHY 1.0 SCOPE AND APPLICATION 1.1 This method is applicable to the determination of the following compounds in drinking water and ground water: _________________________________________________________________ Compound Name CAS No.a 1,2-Dibromoethane (EDB) 106-93-4 1,2-Dibromo-3-chloropropane (DBCP) 96-12-8 _________________________________________________________________ a Chemical Abstract Services Registry Number. 1.2 For compounds and matrices other than those listed in Section 1.1, the laboratory must demonstrate the usefulness of the method by collecting precision and accuracy data on actual samples and provide qualitative confirmation of results by gas chromatography/mass spectrometry (GC/MS). 1.3 The experimentally determined method detection limits (MDL) for EDB and DBCP were calculated to be 0.01 µg/L. The method has been shown to be useful for these analytes over a concentration range of approximately 0.03 to 200 µg/L. Actual detection limits are highly dependent upon the characteristics of the gas chromatographic system, sample matrix, and calibration. 1.4 This method is restricted to use by or under the Supervision of analysts experienced in the use of gas chromatography and in the interpretation of gas chromatograms. Each analyst must demonstrate the ability to generate acceptable results with this method using the procedure described in Section 8.2. 1.5 1,2-Dibromoethane and 1,2-Dibromo-3-chloropropane have been tentatively classified as known or suspected human or mammalian carcinogens.
