| Abstract: | This study established a new gas chromatography method to determine ethylamine in workplace air.A silica gel tube was used to trap ethylamine in the working environment and diluted sufuric acid was used for elution.The se- parating conditions of the chromatographic column,the collection and desorbing of the sample,as well as the interference factors were studied.The method can be used for the determination of ethylamine in workplace air with good results. The accuracy of analysis is 2.3-4.2%,and the detectable limit is 0.011ug/4ul. Sampling efficiency and desorbing efficiency are 99.5% and 98.0%,respectively. |
