| Abstract: | The contents of etox (EO) remained in silicone were analyzed by GC with HP-INNOWAX(crosslinked polyethlene glycol) capillary column as the stationary phase,hydrogen flame ionization detector (FID) as detector,two grade program rise temperature as oven temperature,and external standard method as the quantitative analysis method.The minimum detect quantity is 1ng of EO,the RSD are less than 4.32%,the recovery ratio is in the range of 98.25%-101.84%.This method is convenient,sensitive with good accuracy and precision,so that it can serve well in the quantitative analysis of EO remained in silicone. |
