TGIC中残留环氧氯丙烷的顶空气相色谱测定
TGIC中残留环氧氯丙烷的顶空气相色谱测定 详细信息：

名称：毛细管柱
固定相：5%苯基-95%甲基聚硅氧烷
规格：30m*0.32mm*0.5um
型号：HH-5
应用：TGIC中残留环氧氯丙烷的顶空气相色谱测定

先减压蒸馏,再通过高真空薄膜蒸发器蒸馏除出环氧氯丙烷,粗产品再经过结晶,离心,粉碎和烘干后得到电子级异氰尿酸三缩水甘油酯.处理方法,能有效提高TGIC产品纯度,可以将TGIC的纯度由92%提高到99%以上,达到电子级水平.

TGIC中残留环氧氯丙烷是难挥发性材料中的挥发性组分,顶空分析适用此类物质。浩瀚色谱（山东）应用技术开发有限公司实验采用静态顶空分析,内加法定量.



Determination of Residual Epichlorohydrin in TGIC by Headspace Gas Chromatography
Headspace Gas Chromatographic Determination of Residual Epichlorohydrin in TGIC Details:

Name: capillary column
Stationary Phase: 5% Phenyl-95% Methylpolysiloxane
Specifications: 30m*0.32mm*0.5um
Model: HH-5
Application: Headspace Gas Chromatographic Determination of Residual Epichlorohydrin in TGIC

First vacuum distillation, then through high vacuum thin film evaporator distillation to remove epichlorohydrin, the crude product is then crystallized, centrifuged, pulverized and dried to obtain electronic grade triglycidyl isocyanurate. The treatment method can effectively Improving the purity of TGIC products can increase the purity of TGIC from 92% to more than 99%, reaching the electronic level.

Residual epichlorohydrin in TGIC is a volatile component in less volatile materials, which is suitable for headspace analysis. The experiment of Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopted static headspace analysis and internal addition quantification.
