摘要
以正已烷为萃取剂，用超声萃取方法萃取试样后，采用Agilent7890A／5975C气相色谱／质谱联用仪对柔性篷盖材料中DMEP进行分析。以棉、聚酯纤维、羊毛3种标准贴衬织物为基布，DMEP的最低检出限达0．21ng，回收率在80．2％～103．5％，标准偏差在0．13％-2．70％。
With n-hexane as extrac, tant and using uhrasonic extraction method, DMEP in flexible tenting material was detected by Agilent 7890A/5975C gas chromatography-mass spectrometry. The detection limit of this method can reach 0.21ng with recovery ratio being up to 80.2% - 103, 5% when cotton, polyester and wool standard adjacent fabrics are used as base fabric in this experiment. The standard deviation of this method is between 0. 13% - 2.70%.
