摘要
应用四极质谱仪按ＡＳＴＭＤ２７８６和ＡＳＴＭＤ３２３９分析方法要求对重馏分油的烃类组成进行分析。对仪器的调节、校准，测定的精密度、准确度进行了讨论，方法的相对标准偏差小于０４５，对样品的分析结果与经典的磁质谱分析结果有可比性。通过调节仪器操作条件，四极质谱仪完全可以代替磁质谱用于测定重馏分油的烃类组成。
In the paper,hydrocarbon types of gas_oil have been analyzed by a quadrupole mass spectrometer according to the requirements of ASTM D2786 and ASTM D3239.The adjustment and the calibration of the instrument,as well as the precision and accuracy of the method have been discussed.The value of its relative standard deviation is less than 0.45.The result turned out to be comparable to that of the classical method using magnetic mass spectrometer.By adjusting its operation parameters,the quadrupole mass spectrometer can completely replace magnetic mass spectrometer in determing the hydrocarbon types of gas_oil.
