ABSTRACT
OBJECTIVE: To establish a method for detection of bis(chloromethyl) ether in workplace air using portable gas chromatography-mass spectrometry(GC-MS).METHODS: The sample of bis(chloromethyl) ether in workplace air was collected and detected using the portable GC-MS.The samples were separated by SPB-1 chromatographic column.The mass spectrometry was used for detection,and qualitatively measured by the time and characteristics and quantified by ions peak area.RESULTS: The linear range of bis(chloromethyl) ether was 1.32-66.00 μg/m~3,and the correlation coefficient was 0.999.The detection limit and the lower limit of quantitation were 0.66 and 1.32 μg/m~3 respectively.The spiked recovery for bis(chloromethyl) ether was 96.97%-112.12%.The within-run relative standard deviation(RSD) was6.12%-9.46%.The RSD of different batches samples was 12.31%-19.05%.CONCLUSION: The established GC-MS method for detection of bis(chloromethyl) ether in the air of workplace is of high accuracy and is suitable for rapid qualitative and quantitative detection of bis(chloromethyl) ether in the workplace air.
