| Abstract: | This study established a method for the determination of acrylonitrile using cryogenic pre-concentration followed by GC/MS.The results showed that acrylonitrile was in good linearity within 16.1~4 050 μg/m3, and the correlation coefficient was larger than 0.999.The detection limit was 9.54 μg/m3.Meanwhile, the average recovery, the with-in day and inter-day RSDs also met the requirements of quality control.The recoveries of spiked samples were between 86.9% and 105.3%,which were stable enough to realize extensive use. |
