摘要
建立了以经过蒸馏的高纯度呋喃为外标物,用高效液相色谱测定电力变压器油中呋喃甲醛的方法。该方法加标回收率为86.3%～101.1%,相对标准偏差为5.1%～8.9%。
The authors set up the method of detecting furaldehyde content in power transformer oil by using high efficiency liquid chromatography. This method used distilling high pure furan as external standard substance. The average recovery of the method is 86. 3% - 101.1% with the relative standard deviationof5.1% ~8.9%
