摘要
通过将SP 3 42 0气相色谱仪的填充柱进样口改装成大口径毛细管柱进样口 ,准确地测定了过氧化氢工作液中各组分的含量 ,其相对标准偏差均小于 2 %。达到了工艺试验的要求。
After the injection port has been changed from packed column to capillary column, gas chromatography SP-3420 can be used to analyse the hydrogen peroxide working solution. With high accuracy that RSD is less than 2%.
