名称：毛细管柱

型号：OV-1701

规格：30m*0.25mm*0.25um

温度：280°C

应用：SNT 4373-2015 邻苯二甲酸酐中马来酸酐的测定气相色谱法

浩瀚色谱（山东）应用技术开发有限公司建立了测定苯酐中马来酸酐含量的气相色谱-质谱法。将样品用二氯甲烷溶解,在气相色谱-质谱仪上进行检测,外标法定量。方法的测定下限为10mg.kg-1。对实际样品进行加标回收试验,平均回收率在88.4%～108.7%之间,相对标准偏差（n=8）在2.8%～5.4%之间。该方法操作简便,重现性好,结果准确。

Determination of Maleic Anhydride in Phthalic Anhydride by Gas Chromatography Details:

Name: capillary column

Model: OV-1701

Specifications: 30m*0.25mm*0.25um

Temperature: 280°C

Application: SNT 4373-2015 Determination of maleic anhydride in phthalic anhydride by gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography-mass spectrometry method for the determination of maleic anhydride in phthalic anhydride. The samples were dissolved in dichloromethane, detected on gas chromatography-mass spectrometer, and quantified by external standard method. The lower limit of determination of the method was 10 mg.kg-1. The standard recovery test was carried out on the actual samples, the average recovery rate was between 88.4% and 108.7%, and the relative standard deviation (n=8) was between 2.8% and 5.4%. The method is easy to operate, with good reproducibility and accurate results.
