气相色谱法检测顺酐 详细信息：

名称：填充柱

规格：2m*3mm

型号：HH-Maleic anhydride

应用：工业用顺丁烯二酸酐测定

顺酐在常温下是固体,要制备成溶液才能进行气相色谱分析,所以溶剂的选择极为重要.为此浩瀚色谱（山东）应用技术开发有限公司,选用了稳定性好, 沸点较高的乙腈作为溶剂,利用超声溶解,对生产中粗酐样品进行采样分析,并建立了气相色谱法测定顺酐中杂质含量的分析方法,可有效指导顺酐生产过程中的杂质组分分离,适用于顺酐生产的现场工艺控制.

Detection of Maleic Anhydride by Gas Chromatography
Detection of Maleic Anhydride by Gas Chromatography Details:

Name: Packed column

Specification: 2m*3mm

Model: HH-Maleic anhydride

Application: Determination of maleic anhydride for industrial use



Maleic anhydride is a solid at room temperature, and it must be prepared into a solution for gas chromatography analysis, so the choice of solvent is extremely important. For this reason, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. chose acetonitrile with good stability and higher boiling point as Solvent, using ultrasonic dissolution, sampling and analysis of crude anhydride samples in production, and establishing an analytical method for the determination of impurity content in maleic anhydride by gas chromatography, which can effectively guide the separation of impurity components in the production process of maleic anhydride, and is suitable for maleic anhydride On-site process control of production.
