OV-1701毛细管柱 毛细管柱测定碳酸乙烯酯的纯度

名称：壁涂键合型毛细管柱

固定相：14%氰丙基-苯基-二甲基聚硅氧烷

规格：30m*0.53mm*0.5um
型号：HH-1701
应用：HG∕T5391-2018工业用碳酸乙烯酯

随着近些年对节能及环保的需求日益增加，锂电池的应用亦愈趋广泛。锂离子电 池电解液是由电解质盐以及溶剂两部分组成，碳酸乙烯酯（EC)是电解液中重要的溶剂。溶 剂中的杂醇在电池充放电循环中，可能诱发自由基反应，加速溶液分解影响电池性能的稳 定，因此准确测定碳酸乙烯酯中杂醇的含量有着重要的意义。


浩瀚色谱（山东）应用技术开发有限公司，采用毛细管柱，面积归一法定量工业用碳酸乙烯酯的含量，柱效高，分离好，结果满意。

Determination of the Purity of Ethylene Carbonate by Capillary Column
Purity of Ethylene Carbonate by Capillary Column Details:

Name: Wall-coated bonded capillary column

Stationary phase: 14% cyanopropyl-phenyl-dimethylpolysiloxane

Specifications: 30m*0.53mm*0.5um
Model: HH-1701
Application: HG∕T5391-2018 Industrial Ethylene Carbonate

With the increasing demand for energy saving and environmental protection in recent years, the application of lithium batteries has become more and more extensive. Lithium-ion battery electrolyte is composed of electrolyte salt and solvent, and ethylene carbonate (EC) is an important solvent in the electrolyte. The fusel alcohol in the solvent may induce free radical reaction during the battery charge-discharge cycle, accelerate the decomposition of the solution and affect the stability of the battery performance. Therefore, it is of great significance to accurately determine the content of fusel alcohol in ethylene carbonate.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts capillary column and area normalization method to quantify the content of industrial ethylene carbonate, with high column efficiency, good separation, and satisfactory results.
