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。
The relative standard deviation (RSD) of each component in the hydrogen peroxide working solution was accurately determined by modifying the packed column inlet of the SP 3 42 0 gas chromatograph into a large-diameter capillary column inlet with relative standard deviations less than 2%. Reached the technical test requirements.
