【摘要】 利用气相色谱法对胶黏剂中苯、甲苯、二甲苯进行了测定,当苯含量为24.21 g/kg时,扩展不确定度U=1.42 g/kg,(K=2);甲苯含量为23.86 g/kg时,扩展不确定度U=1.22 g/kg,(K=2);二甲苯含量为63.80 g/kg时,扩展不确定度U=1.22 g/kg,(K=2)。更多还原

【Abstract】 In this paper,benzene,toluene and xylene in adhesive were determined by using gas chromatography,when benzene content is 24.21 g/kg,the expanded uncertainty U=1.42 g/kg,(K=2);Toluene content is 23.86 g/kg,the expanded uncertainty U=1.22 g/kg,(K=2);Xylene content is 63.80 g/kg,the expanded uncertainty U=1.22 g/kg,(K=2).更多还原
