IPB组成份的气相色谱分析

Gas Chromatography for Analysing Component of IPB Impregnant

本文叙述了用HP5880A气相色谱仪及涂二甲基硅氧烷固定液的填充色谱柱,很好地分离了电力电容器浸渍剂IPB中的间、对、邻位异构体以及多取代物,从而可以探索电力电容器性能与IPB浸渍剂组成份之间的关系。用检查间位含量及间、对位总含量的办法控制IPB的质量,以进一步确保电力电容器的产品质量。本文使用填充柱气相色谱的理论基础范德姆特(Van Deemter)速率理论方程式,计算了本实验分离m-IPB的理论塔板数和理论塔板高度以及分离m-IPB和p-IPB的分离度。随后对本实验测定数据作了误差分析。

This paper describes that m-IPB, p-IPB and o-IPB isomer capacitor imPregnant have been so well separated with HP5880A Chromatographic instrument and packed column of dimethylsilicone stationary phase that the relationship between the ProPerties of Power eapacitor and the components of IPB imPregnant can be explored. With. the method of checking content of m-IPB as well as total amount of m-IPB and p-IPB to control the quality of IPB, it can be expected to insure the quality of power capacitor products The Van Deemter Rate Equation, called basis theory of packed column, is used in calculating The Number of Theoretical Plate and HETP (Height Equivalent of Theoretical Plate) as well as Resolution between m-IPB and p-IPB in this experiment. Moreover, error analysis for determinating data is made hereafter.
