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.
