用气相色谱法/质谱法测定成品汽油中苯、甲苯和总芳烃的试验方法

Standard Test Method for Determination of Benzene,Toluene,and Total Aromatics in Finished Gasolines by Gas Chromatography/Mass Spectrometry

适用范围:<p>Test methods to determine benzene and the aromatic content of gasoline are necessary to assess product quality and to meet fuel regulations.</p> <p>This test method can be used for gasolines that contain oxygenates (alcohols and ethers) as additives. It has been determined that the common oxygenates found in finished gasoline do not interfere with the analysis of benzene and other aromatics by this test method.</p><p id="s00002">1.1 This test method covers the determination of benzene, toluene, other specified individual aromatic compounds, and total aromatics in finished motor gasoline, including gasolines containing oxygenated blending components, by gas chromatography/mass spectrometry (GC/MS).</p> <p id="s00003">1.2 This test method has been tested for the following concentration ranges, in liquid volume percent, for the following aromatics: benzene, 0.1 to 4 %; toluene, 1 to 13 %; and total (C6 to C12) aromatics, 10 to 42 %. The round-robin study did not test the method for <span class="italic">individual</span> hydrocarbon process streams in a refinery, such as reformates, fluid catalytic cracked naphthas, and so forth, used in the blending of gasolines.</p> <p id="s00004">1.3 Results are reported to the nearest 0.01 % for benzene and 0.1 % for the other aromatics by liquid volume.</p> <p id="s00005">1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.</p> <p id="s00006">1.5 <span class="italic">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 its use.</span>
