呋喃甲醛检测条件及优化

Furaldehyde detect conditions and optimization

介绍了检测呋喃甲醛含量的高效液相色谱分析法,利用其含量值来间接反映电力设备中绝缘纸的老化程度。为电力设备安全稳定运行提供了保障,考察了优化条件下检测结果的精密度和多组分色谱峰的分离度。本方法相对标准偏差小,可以应用于变压器油样品中呋喃甲醛含量的检测。结果表明,液相色谱法灵敏、可靠、稳定、重现性好,对全部种类的变压器油均适用。

We found the method of detecting furaldehyde content in power transformer oil, using content unstraight reflect insulate paper＇s aging in electric equipment.For the safe and stable operation of power equipment has provided a guarantee.Examined the test results under the optimum conditions of precision and multi-compo- nent peaks in separation.This method is small relative standard deviation.andCan be used in transformer oil sampies Furan Detection of formaldehyde content.The results showed that sensitive and reliable liquid chromatography stability, good reproducibility.For all types of transformer oil apply.
