三甲胺是大气环境,特别是室内环境需要进行严格控制的恶臭污染物之一。航行期间,船员需长期暴露在舰船舱室环境中,当系统运行或材料使用释放三甲胺时,可能对人员感受和健康造成严重危害。


浩瀚色谱（山东）应用技术开发有限公司研究了应用苏码罐采样-气相色谱/质谱(GC/MS)在舰船舱室环境中测定三甲胺含量的方法,并对某型疑似出现三甲胺释放的舰船舱室中三甲胺含量进行了调查研究。方法利用苏码罐采集舰船典型舱室部位,特别是疑似存在三甲胺释放部位的环境空气样品,通过预浓缩仪浓缩-气相色谱质谱分析,建立苏码罐采样-气相色谱-质谱法测定舰船舱室环境空气中的三甲胺检测方法。结果通过优化色谱柱型、色谱柱温度、预浓缩温度和进样量等试验条件,采用苏玛罐-气相色谱-质谱法可以有效检测舰船舱室环境中的三甲胺浓度。主要仪器参数为:色谱柱HH-Tamine60甲胺专用毛细管柱；进样口温度:180℃,不分流进样；柱流速:1.4mL/min；柱温:35℃保持,5min,然后以5℃/min升温150℃,保持7min,再以10℃/min升温200℃,保持4min；冷阱浓缩仪取样体积400ml；一级冷阱烘烤温度150℃；烘烤时间10min；二级冷阱烘烤温度220℃；烘烤时间10min；三级聚焦烘烤温度150℃；烘烤时间10min；在此条件下,空气中三甲胺的检出限为0.8 ug/m~3,相关系数>0.9992,线性范围为0～10~3 ug/m~3。

Determination of Trimethylamine in the Atmosphere of Ship Cabins by Gas Chromatography Mass Spectrometry

Details of determination of trimethylamine in the atmosphere of ship cabin by gas chromatography-mass spectrometry:



Name: HH-Tamine60 methylamine special capillary column

Specification: 60m * 0.32mm

Operating temperature: 280 ° C

No.: 20220109001



Trimethylamine is one of the malodorous pollutants that need to be strictly controlled in the atmospheric environment, especially in the indoor environment. During the voyage, the crew members need to be exposed to the cabin environment of the ship for a long time. When the system operation or material use releases trimethylamine, it may cause serious harm to the feeling and health of personnel.




Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied the method of determining the content of trimethylamine in the cabin environment of a ship by using Sumar tank sampling gas chromatography/mass spectrometry (GC/MS), and investigated the content of trimethylamine in the cabin of a ship suspected of releasing trimethylamine. Methods Environmental air samples were collected from typical cabins of ships, especially those suspected to have trimethylamine release. A method for the determination of trimethylamine in the ambient air of ship cabins was established by preconcentrator concentration gas chromatography-mass spectrometry. Results By optimizing the column type, column temperature, preconcentration temperature and sample volume, the Suma tank gas chromatography-mass spectrometry can effectively detect the concentration of trimethylamine in the cabin environment of ships. The main instrument parameters are: chromatographic column HH-Tamine60 methylamine special capillary column; Injection port temperature: 180 ℃, no split injection; Column flow rate: 1.4 mL/min; Column temperature: 35 ℃ for 5min, then 5 ℃/min to 150 ℃ for 7min, then 10 ℃/min to 200 ℃ for 4min; The sampling volume of the cold trap concentrator is 400ml; The baking temperature of the primary cold trap is 150 ℃; Baking time 10min; The baking temperature of the secondary cold trap is 220 ℃; Baking time 10min; The three-stage focus baking temperature is 150 ℃; Baking time 10min; Under this condition, the detection limit of trimethylamine in air is 0.8 ug/m~3, the correlation coefficient is>0.9992, and the linear range is 0~10~3 ug/m~3.
