| 摘 要： | 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2.5 mg/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。

| Abstract: | 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 environment. 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. |
