| 中文摘要 |
| 介绍测定5种残余单体的顶空分析方法。采用高压顶空进样技术,研究高压顶空的测定条件。方法操作简单,无需对样品进行预处理,线性范围103-104,精密度RSD<5%,检出限<1μg/g. |
| 英文摘要 |
| 5 Residual monomers were detected successfuly by using high pressure sampling accessory in headspace.Predisposal for samples is not necessary.It was showed that the linear range is 103—104,the relative standard deviation is lower than 5%(n=8)and the relative coefficients are 0.9906,0.9995,0.9987,0.9996 and 0.9961 for VAC,EA,MMA,BA and ST respectively.The detection limit is less than 1 μg/g. |
