目的 研究复杂气氛下痕量油雾的测量方法,测量某船舱室空气中油雾的成分和浓度.方法 采用溶液富集法采集舱室空气中油雾,采用气相色谱-质谱联用对油雾成分及含量进行准确测定.结果 某船舱室中油雾成分主要包括正十三烷、正十三烷酸、正十二烷,油雾的质量浓度最高值在2.5mg/m3左右,测量不确定度为16.92％,浓度符合舱室环境要求.结论 结合溶液富集法和气相色谱-质谱联用分析方法可以测定复杂气氛下痕量油雾成分和浓度.%Objective To study the method for measuring trace oil mist in complex atmosphere, and to measure the composition and concentration of oil mist in a ship cabin.Methods The oil mist in the cabin air was collected by solution enrichment method. The composition and content of oil mist were determined by gas chromatography-mass spectrometry. Results The oil mist in cabin included n-tridecane, tridecane acid, n-dodecane; the oil mist concentration was the highest at about 2.5mg/m3, the measurement uncertainty was 16.92％, the concentration met the requirement on cabin environ-ment.Conclusion The concentration and concentration of trace oil mist in complex atmosphere can be determined by gas chromatography and mass spectrometry combined with solution enrichment method.
