《GB/T 18340.4-2001地质样品有机地化测试 重馏份石油芳香烃族组成质谱分析方法》由TC93(全国自然资源与国土空间规划标准化技术委员会)归口,主管部门为自然资源部(国土)。
本标准规定了重馏分石油芳香烃族组成的质谱分析方法、定量计算过程和分析精密度等。
Scope
This standard specifies the mass spectrometry analysis method, quantitative calculation process and analysis precision of aromatic hydrocarbons in heavy fraction petroleum. This standard is applicable to the quantitative analysis of the hydrocarbon group composition of 18 aromatic hydrocarbons and 3 aromatic thiophenes in the aromatic fraction of heavy distillate petroleum (boiling range 300°C to 540°C). There should be no olefins in the sample, the total sulfur content must be less than 1% of the total weight, and the non-aromatic content should be <5%.
