| 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. |
