Determination of Impurities in Maleic Anhydride by Gas Chromatography

Name: Packed column

Specification: 2m*3mm

Model: HH-Maleic anhydride

Application: Determination of maleic anhydride for industrial use


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a gas chromatography internal standard method to determine the total content of maleic anhydride and the detection method of impurity content. It is separated by gas chromatography and detected by hydrogen flame ionization detector. The experimental results show that the chromatographic peak resolution of the main component of maleic anhydride and each impurity is good, the relative standard deviation of each impurity content is below 1.0%, the linear correlation coefficient is greater than 0.999, and the recovery rates are all 90.0%-110.0% between. The method is suitable for the production process of producing maleic anhydride by catalytic oxidation of n-butane as raw material and the needs of downstream users.
