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.
