名称：填充柱
固定相：多孔聚合物

规格：2m*3mm

粒度：60-80目

型号：GDX-101

应用：药典2015溶剂残留测定

浩瀚色谱（山东）应用技术开发有限公司建立了一种香兰素中残留有机溶剂乙醇含量的气相色谱方法。方法采用气相色谱法对香兰素中乙醇的含量进行了测试;并参照《中国药典》;2010版附录中XIXA和有机溶剂残留的指导原则对测定方法精确性、准确度等方面进行了评价。结果线性和范围:0.0107~0.1495mg/mL,R2=0.9995;重复性:SD(%)=0.61%,平均回收率99.42%;稳定性:样品在12 h内主峰面积稳定,RSD(%)=0.88%;耐用性:检测器、进样口温度、柱温在温度上波动±5℃对测试影响较小。结论经方法学验证,该法简便快捷灵敏度高结果准确,适用于香兰素中乙醇的检测。

Determination of ethanol residue in vanillin standard substance
Determination of ethanol residue in vanillin standard substance Details:

Name: Packed column
Stationary phase: porous polymer

Specification: 2m*3mm

Granularity: 60-80 mesh

Model: GDX-101

Application: Determination of solvent residues in Pharmacopoeia 2015

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a gas chromatography method for the residual organic solvent ethanol content in vanillin. Methods Gas chromatography was used to test the content of ethanol in vanillin. The accuracy and accuracy of the determination method were evaluated in accordance with the guidelines for XIXA and organic solvent residues in the appendix of the Chinese Pharmacopoeia in the 2010 edition. Linearity and range of results: 0.0107~0.1495mg/mL, R2=0.9995; Repeatability: SD(%)=0.61%, average recovery rate 99.42%; Stability: The main peak area of the sample is stable within 12 hours, RSD(%)= 0.88%; Durability: The temperature fluctuation of the detector, the inlet temperature, and the column temperature of ±5℃ has little effect on the test. Conclusion The method has been verified by methodology, the method is simple, rapid, sensitive, accurate, and suitable for the detection of ethanol in vanillin.
